TECHNICAL FIELD
The present disclosure is directed to wall system components, and, more specifically, to casing accessories for multi-component wall systems.
BACKGROUND
A recent development in the construction industry is the growing popularity of continuous insulation, which is designed to extend across structural members in a continuous manner and configured to minimize thermal bridging. Some popular types of continuous insulation include rigid foam, mineral wool, biomass, and wood insulation, any of which can be installed on the exterior side of the structural members of a building construction. With the advent of continuous insulation as a frequent requirement in wall construction of new building products, various issues have arisen including those relating to the effectiveness of fire protection, moisture management, the maintenance of edge integrity of the wall assembly after installation, and the management of variations in wall assembly thickness during installation. For wall systems incorporating continuous insulation, moisture management becomes an important issue due to the lack of openings in the continuous layer that would otherwise allow for movement of moisture from interior to exterior portions of the wall assemblies. Variation in the thickness of different insulation panel products result in installed wall assemblies varying in thickness from one building to another. For manufacturers of wall systems and accessories, such as starter tracks, variations in wall thickness from one installation to another necessitate the need to produce different versions of a given accessory in order to accommodate the varying thicknesses, thereby potentially increasing manufacturing and inventory costs. Furthermore, wall assemblies containing continuous insulation often are thicker than wall assemblies containing traditional types of insulation resulting in thicker assembly edges that are more prone to wear and tear.
Other challenges arise in the area of wall assemblies and construction. For example, fire safety has always been an issue in construction. With the advent of modern materials and construction techniques, the need for construction features and components that can tend to resist the spread of fire has persisted. Furthermore, the constructability of wall systems has been and continues to be a target for improvements. Oftentimes, adjustments to wall assemblies at the time of installation are necessary to achieve the desired appearance, performance and durability of the finished product. Yet current designs of wall systems often do not provide the necessary flexibility to achieve such adjustments efficiently or effectively. Additional challenges include water management, not just in installations with continuous insulation panels, but other wall systems that are exposed to weather.
Consequently, there is a need for wall accessories that can address one or more of these and related issues. The present disclosure addresses this need and provides additional aspects that can prove useful in the construction industry.

The flange can provide an angled surface for moisture to flow downward and away from the face of the multi-component wall system with which the casing accessory 10 is used. The retaining wall 22 further comprises a mesh layer 62 that extends the length of the retaining wall 22 and is aligned parallel to the mounting bracket 42. The mesh layer 62 can improve the adherence of other layers of a wall system to the insulation panel partially encased by the casing accessory 10. The casing accessory 10 includes a channel 36 formed by the cooperation of the retaining wall 22, the spacer 24, the receiver 46, and the mounting bracket 42. The channel 36 can extend the length of the casing accessory 10 and is configured to receive one or more components, such as insulation panels, of a multi-component wall system. The width of the channel 36 is defined by the sidewalls thereof, which are formed by the mounting bracket 40 and the retaining wall 22. The channel width is adjustable and can be adjusted by adjustment of the spacer 24 in order to accommodate multi-component wall systems of varying depth.
As shown in FIG. 1, the front component 20 is connected to the rear component 40 by the attachment of the rear portion of the spacer 24 to the receiver 46 of the rear component 40. The receiver 46 is connected to and integrally formed with the mounting bracket 42, which, as shown in FIG. 1, is a wall extending the length of the casing accessory 10. The receiver 46 comprises a first receiver wall 48 and a parallel second receiver wall 50. As shown in FIG. 4A, a receiver slot 51 is formed between the first receiver wall 48 and the second receiver wall 50 and can extend the length of the rear component 40. The rear portion of the spacer 24 can be inserted into the receiver slot 51 and frictionally retained therein to connect the front component 20 to the rear component 40. In addition to the frictional retention of the spacer 24 in the slot 51, alternative means of fastening the front component 20 to the rear component 40 can be provided and are contemplated by the present disclosure. For example, one or more mating dimples, not shown, located on the spacer 24 and on one or both of the first receiver wall 48 and second receiver wall 50 can be provided to fasten the front component 20 to the rear component 40. Alternatively, catches, hooks, adhesives or other fasteners can be employed to attach the front component 20 to the rear component 40.
FIG. 2A shows a perspective view of the rear component 40 of the casing accessory 10. The rear component 40 includes the mounting bracket 42, which has a plurality of optional fastener apertures 44 positioned at intervals along its length. The mounting bracket 42 comprises an upwardly extending wall; however, the casing accessories of the present disclosure can include other structures that serve as brackets for mounting the casing accessory to a wall support structure. For example, the mounting bracket 42 can include one or more merlons forming a crenellation along the length of the casing accessory 10. The present disclosure encompasses alternative structures imparting sufficient strength to the casing accessory to receive and support one or more portions of a multi-component wall system. The first receiver wall 48 of the receiver 46 can provide a surface upon which one or more components of a multi-component wall system can be positioned as the multi-component wall system is installed. In one example, the rear component 40 can include a mounting bracket 42 of approximately three inches (76 mm) in height and a receiver 46 extending approximately one inch (25 mm) from the mounting bracket 42.
FIG. 2B shows another example of a rear component 340 that can be used in casing accessories encompassing aspects of the present disclosure. Like the rear component 40, shown in FIG. 2A, the rear component 340 includes a mounting bracket 342 with a plurality of optional fastener apertures 344 formed therein and a receiver 348 extending from a lower portion thereof. The receiver 348 includes a receiver 346 positioned above a second step 350, which extends below and outward therefrom. The rear component 340 can have dimensions similar to those of the rear component 40 set forth in FIG. 2A. Likewise, the mounting bracket 342 and the retainer 346 of rear component 340 can be aligned to form angles within ranges similar to those formed by the parts of the rear component 40 set forth in FIG. 2A and other rear components described herein. The alignment of the first and the second steps 346 and 350 forms a seat 352 on which the spacer 24 of a front component 20 can be positioned or aligned, when operably connecting the front and rear components of a casing accessory.
As shown in FIG. 3, the front component 20 includes a spacer 24 in which is formed a plurality of drainage holes 26 spaced along its length and arranged to provide pathways through which moisture can drain from an interior portion of a multi-component wall system. Also provided on the spacer 24 are one or more width adjusters 30 that can serve as part of the support structure of the spacer 24 and optionally can be detached or folded so to allow for the reduction in the width of the spacer 24. In one example, the front component 20 includes one or more score lines 28 extending along a least portion of the length of the spacer 24 and delineating the plurality of width adjusters 30 that take the form of detachable members. As shown in FIG. 3, seven score lines 28 are disposed intermittently along the width of the spacer 24. The score lines 28 can be provided at pre-determined points along the width of the spacer 24; for example, the score lines 28 can be spaced approximately one inch or 25 mm apart with the first score line 28 beginning approximately 25 mm from one edge of the spacer 24. The score lines 28 can be evenly distributed across the entire surface of the spacer 24, or, as shown in FIG. 3, the score lines can be distributed across a major portion of the surface of the spacer 24. Alternatively, the score lines 24 can extend over less than a majority of the width of the spacer 24. The score lines 24 can be continuous lines extending the length of the spacer 24 or can be intermediate dashed lines extending across the length of the spacer 24 to the exterior edges of the spacer 24.
The score lines 28 define a plurality of the width adjusters 30 formed in the spacer 24 of the front component 20. Unlike the views of the front component 20 shown in FIGS. 1, 5, and 6, FIG. 3 shows the front component 20 with all of the width adjusters 30 attached to the spacer 24 as originally manufactured. The width adjusters 30 can be of equal width, as shown in FIG. 3, or, alternatively, of differing width depending upon the intended use of the accessory. The width adjusters 30 can be of predetermined width, for example one inch or approximately 25 mm. Indicia, not shown, indicating the width of each width adjuster 30 can be provided on or formed in the spacer 24 to aid the installer in determining the appropriate width of the spacer 24. The adjustability of the spacer 24 allows for the width of the channel 36 to be adjusted in order to provide the optimal width to support or encase the multi-component wall system in which the casing accessory 10 is to be used. In the front component 20 shown in FIG. 3, each width adjuster 30 can be folded or detached from the front component 20 by breaking or cutting the strip along the score lines 28. The adjustability of the spacer 24 allows for the spacer 24 to be configured into eight different widths by folding or removing the appropriate number of width adjusters 30. While the width adjusters 30 shown in FIG. 3 take the form of strips that are delineated by score lines 28, the present disclosure also encompasses detachable members with alternative configurations but that can be removed to adjust the width of the spacer and the adjustable channel width of the casing accessory.
In one example, the front component 20 can include a spacer 24 approximately five inches (127 mm) in width with seven width adjusters 30 formed therein, each approximately one half inch (13 mm) in length. The spacer 24 includes a non-scored section approximately one and one half inch (38 mm) in width disposed between the retaining wall 22 and the first score 28. The retaining wall 22 includes a plurality of drainage holes approximately 3/16 of an inch (5 mm) in diameter and aligned every three inches (76 mm) on center.
FIG. 4A shows a side view of the rear component 40 including the mounting bracket 42, and the receiver 46 formed of the first receiver wall 48 and the second receiver wall 50 and having a receiver slot 51 formed therein. A first angle 55 is shown in FIG. 4A extending from the mounting bracket 42 to the first receiver wall 48. This first angle 55 can vary by degree depending upon the desired configuration of the channel 36 formed in the casing accessory 10. In one aspect, the angle 55 between the mounting bracket 42 and the receiver 46 can be greater than or equal to about 90°. In another aspect, the angle 55 can be about 95°. In still a further aspect, the angle 55 can be in a range of about 90° to about 100°. In yet another aspect, the angle 55 can be in the range of about 90° to about 105°. With angle 55 being at an angle of 90° or greater, the casing accessory 10 can provide drainage away from interior portions of the wall system outward to the outer surface of the wall system. The first and the second receiver walls 48 and 50 can be of different lengths.
FIG. 4B shows a side view of the rear component 340 shown in FIG. 2B. The first step 346 extends from the mounting bracket 342 and can be aligned at about 90° angle thereto. The second step 350 extends away from the first step 346 and the mounting bracket 342 and can form a seat 352 with the cooperation of the first step 346. In one embodiment, the second step 350 extends a length of approximately 25 mm or one inch measured from the rear edge of the rear component 340. The first step can extend approximately 8 mm or one third of an inch form the rear surface of the rear component 340. The seat 352 can receive a portion of a receiver formed on a front component so as to operably connect the rear component to the front component to form a casing accessory.
FIG. 5A shows the front component 20 with some of the width adjusters 30 removed from the spacer 24. The front component 20 includes a retaining wall 22 extending upward from the spacer 24. The retaining wall includes a mesh layer 62. The mesh layer 62 is aligned parallel to the mounting bracket 42 of the rear component 40 when the front and rear components 20 and 40 are operably connected. The second angle 53 formed between the retaining wall 22 and the spacer 24 can be less than or equal to about 90°. In another aspect, the angle 53 can be in the range of about 80° to about 90°. In still a further aspect, the angle 53 can be in the range of about 75° to about 90°. In yet another aspect, the second angle 53 can be about 85°. The flange 32 extends downward and away from the spacer 24. The angle between the front face of the retaining wall 22 and the flange 32 can be greater than or equal to about 90°. The second angle 53 and the first angle 55 can be configured to total 180° when the front component 20 is operably connected to the rear component 40, thereby making the first angle 55 and the second angle 53 supplementary angles. When the first angle 55 and the second angle 53 are supplementary angles the mounting bracket 42 can be parallel to the retaining wall 22. The present disclosure also encompasses casing accessories in which the first angle 55 and the second angle 53 are not supplementary angles and accessories in which the mounting bracket and the retaining wall are not aligned in parallel.

FIG. 11 shows yet another embodiment of a casing accessory encompassing aspects of the present disclosure. The casing accessory 200 includes a first leg and a second leg that are aligned to form a 90° angle. Casing accessories having a first and a second leg formed therein and encompassed by the present disclosure can form angles other than right angles as necessary to encase the edges of the wall assembly components with which the accessories are used. The two-leg casing accessory 200 can be installed adjacent a door, a window, or other types of interruptions in a wall surface and can encase the edges of the wall assembly components abutting these interrupting structures. The casing accessory 200 has a channel 236 formed therein. The channel 236 has an angle of about 90° formed therein and made up of the first channel leg 237 and the second channel leg 238. The channel 236 also includes an adjustable channel width 239 that extends from the first mounting bracket 242 to the first retaining wall 222, and, likewise, from the second mounting bracket 245 to the second retaining wall 223. The adjustable channel width 239 is adjustable by adjustment of the first and the second spacer legs 224 and 225.
The casing accessory 200 includes a front component 220 operably connected to a rear component 240. Both the front component 220 and the rear component 240 have a 90° angle formed therein and mate to form the 90° channel 236. The configuration of the front component 220 and the rear component allow for encasement of the edges of one or more components of a wall assembly at a corner formed along the wall structure. The front component 220 includes the first retaining wall 222 and the second retaining wall 223. The first retaining wall 222 is attached to the second retaining wall 223 and in combination with the retaining wall 223 forms an angle of approximately 90°. Each of the first and the second retaining walls 222 and 223 have a plurality of mating holes 227 formed therein. The mating holes 227 allow for the bonding of coating components used in the wall assembly with the surface of the wall assembly component positioned in the accessory channels. The front component 220 includes a spacer having a 90° angle formed therein and comprised of the first spacer leg 224 and the second spacer leg 225. The first retaining wall 222 is attached to and extends from the first spacer leg 224, and the second retaining wall 223 is attached to and extends from the second spacer leg 225. From the first retaining wall 222 extends a first flange 232 and from the second retaining wall 223 extends a second flange 233. The first and the second flanges 232 and 233 are configured to support a mesh layer thereon. Attached to the first component 220 is a mesh layer having a 90° angle formed therein. The first and the second spacer legs 224 and 225 can include one or more strips formed therein and similar to the width adjusters 30 formed on the spacer 20 shown in FIG. 3. Scores similar to those scores can separate these strips 28 shown in FIG. 3.
The rear component 240 includes a mounting bracket 242 having a 90° angle formed therein and comprising a first bracket leg 243 and a second bracket leg 245. Each of the first and the second bracket legs 243 and 245 have a plurality of fastener holes 244 formed therein to receive fasteners to secure the accessory 200 to a wall support structure. The mounting bracket 240 is integrally formed with a receiver that includes a first receiver leg 246 and a second receiver leg 247. Within the receiver is a receiver slot 251 into which the first and second spacer legs 224 and 225 can be inserted to operably connect the first component 220 to the second component 240.
FIGS. 12-19 illustrate another embodiment of a casing accessory encompassed by the present disclosure. The casing accessory 500 includes a plurality of drainage canals 580 disposed at the base of the channel 536 to allow for water and moisture to drain away from the wall support structure to which the accessory 500 is mounted and to drain toward an outer surface of the multi-component wall system of which the accessory 500 is a part. The drainage canals 580 include a first end aligned proximal to the mounting bracket 542 and a second end aligned distal to the mounting bracket 542. Water can flow from the first end to the second end and outward from the multi-component wall system. The front component 520 and the rear component 540 when installed in a multi-component wall system are aligned so that the rear component 540 is proximal the underlying wall support structure to which the accessory 500 is mounted and the front component 520 is aligned distal to the underlying wall support structure. Furthermore, the front component 520 is aligned proximal to the outer surface of the multi-component wall system and the rear component 540 is aligned distal to an outer surface of the multi-component wall system of which the accessory 500 is a part. The front component 520 and the rear component 540 can be manufactured as two separate components and then operably combined after manufacturing, such as at the time of installation to form the casing accessory 500 that has a channel 536 formed therein.
The front component 520 includes a retaining wall 522 extending a majority of the length of the casing accessory 500. The retaining wall 522 includes a plurality of mating holes 527 formed therein to allow layers of a multi-component wall system disposed on the outside of the retainer wall 522 to adhere to components disposed inside the retaining wall 522. A flange 532 depends from the retaining wall 522 and is angled away from the rear component 540 to allow water and moisture to drain away from the casing accessory 500 and the underlying support structure to which the casing accessory 500 is mounted. The flange 532 extends a majority of the length of the front component 520. The front component 520 also includes a receiver 534 depending from the retaining wall and extending away from the flange 532. The receiver 534 comprises a shelf 538 extending along at least a portion of the length of the front component 520 and can extend the length of the front component 520, as shown in FIG. 12. The receiver 534 engages a spacer 524 integrally formed in the rear component 540. The spacer 524 and the receiver 534 cooperate to establish and maintain the adjustable channel width 535 of the channel 536 formed by the rear component 540 and the front component 520.
The spacer 524 includes a spacer base 525 that extends from the bottom of the mounting bracket 542 to the front edge 523 of the rear component 540. Extending from the spacer base 525 is a plurality of drainage walls 568 aligned parallel to each other and perpendicular to the length of the channel 536. Each adjoining pair of drainage walls 568 cooperate to form a drainage canal 580 that extends along at least a portion of the spacer 524 and that open at the front edge 523 to allow water or moisture to flow from the mounting bracket 524 out from the front edge 523. The drainage canals 580 open toward and under the retaining wall 522 and the flange 532. As shown in FIGS. 15 and 16, the drainage walls 568 and the adjacent drainage canals 580 extend the width of the base 525 of the spacer 524 and are aligned generally perpendicular to the mounting bracket 542. The plurality of drainage canals 580 are aligned so that water can drain away from the frame or substrate to which the mounting bracket 542 is attached and outward from the multi-component wall system wall of which the casing accessory 500 is a part when installed.
As shown in FIGS. 12 and 15-19, each drainage wall 568 can include a step 570 disposed adjacent the mounting bracket 542 and having a height greater than the remainder of the drainage wall 568. The walls 572 formed adjacent the mounting bracket 542 can cooperate to form an abutment 573 that prevents the components of a multi-component wall system from contacting the mounting bracket 542, and thereby creating a drainage gap 765 between the wall component insulation panel 760 and the underlying wall support structure 770. The top surfaces of the drainage walls 568 cooperate to form a support surface 575 aligned above the drainage canals 580 and which support at least a portion of the receiver 534, such as the shelf 538, and/or a portion of one or more components of a multi-component wall system disposed in the channel 536 of the casing accessory 500 so that the component that is supported is spaced apart from the spacer base 525 and above the drainage canals 580.
FIGS. 14 and 19 illustrate an angle 553 formed by the retaining wall 522 and the receiver 534 and that is interior to the channel 536 when the front component 520 is operably connected to the rear component 540. The angle 553 can be less than or equal to about 90°. Alternatively, angle 553 can be in the range of about 75° to about 90°. FIGS. 17 and 19 illustrate an angle 555 formed by the mounting bracket 542 and the spacer base 525 and that is interior to the channel 536 when the front component 520 is operably connected to the rear component 540. Angle 553 can be greater than or equal to about 90°. Alternatively, angle 555 can be in the range of about 90° to about 105°. In another aspect, angle 553 can be less than or equal to angle 555. The configuration of the rear component 540 so that angle 555 is greater than about 90° provides a surface of the spacer base 525 at the bottom of each drainage canal 580 to slope down and away from the underlying wall support structure to which the mounting bracket 542 is mounted, thereby allowing water to flow down and away from the wall support structure by gravity.
FIG. 14 illustrates that the receiver 534 can include one or more width adjusters 530 that are formed thereon. The width adjusters 530 can be separated by score lines 528 and are configured to be bent, folded or removed so as to adjust the width of the receiver 534 and thereby adjust the channel width 535 of a channel 536 formed by the cooperation of the receiver 534 with the spacer 524. Accordingly, it should be understood that the present disclosure encompasses casing accessories that include channels having adjustable channel widths that are adjustable by adjustment of either the spacer alone, the receiver alone, or both the receiver and spacer. Furthermore, it should be understood that within the present disclosure the term spacer encompasses structures identified as spacers herein, as well as structures identified as receivers herein and/or combinations thereof.
FIGS. 16 and 17 illustrate the rear component 540 and the aspects of the spacer 524 that allow for adjustment of the width thereof to provide an adjustable channel width 535 of appropriate distance for use in a multi-component wall system and that can adjusted and set at the time of connection of the front component 520 to the rear component 540 by configuring one or more width adjusters 550. The spacer 524 includes a plurality of width adjusters 550 formed therein and which include portions of both the spacer base 525 and the drainage walls 568. The width adjusters 550 are delineated by score lines 551 formed in the spacer 524 and that extend through both the base 525 of the spacer 524 and the drainage walls 568 formed thereon. When a channel 536 of a particular width is desired, the width adjusters 550 can be removed to reduce the spacer 524 to adjust the adjustable channel width 535 to the appropriate width to receive and encase one or more components of a multi-component wall system.
FIGS. 18 and 19 shows the casing accessory 500 mounted on an underlying wall support structure 770 and forming a part of a multi-component wall system 800. The casing accessory 500 is mounted to the wall support structure 770 by a fastener 710, such as a nail, disposed in fastener aperture 544 formed in the mounting bracket 542. The mounting bracket 542 is aligned adjacent the wall support structure 770 and the spacer 524 extends outwardly therefrom. The front component 520 is operably connected to the rear component 540 by engagement of the receiver 534 with the spacer 524, such that the receiver 534 is disposed on the support surface 575 formed by the top surfaces of the drainage walls 568, thereby creating a support structure for holding an edge of the insulation panel 760. The spacer 524 and the receiver 534 cooperate to form the base of the channel 536 formed by the casing accessory 500. The drainage canals 580 formed between the drainage walls 568 are disposed at the base of the channel 536 below the continuous insulation panel 760. A mesh layer 762 is disposed on both the continuous insulation panel 760 and the retaining wall 522 of the front component 520. Additional layers 764 and 766 are disposed over the other components of the system. When installed, the insulation panel 760 can be rested on top of the steps 570 formed on the drainage walls 568 adjacent the mounting bracket 542, thereby forming a gap below the bottom of the insulation panel 760 and the top of the drainage walls 568 to allow for the insertion of the receiver 534 of the front component 520 between the insulation panel 760 and the drainage walls 568. When the insulation panel 760 is so aligned in the channel 536 with a gap 765 in between the rear face of the insulation panel and the mounting bracket 542, water and moisture can flow downward by gravity from within the multi-component wall system 800 through the drainage gap 760 to the drainage canals 580. The water can then flow outward to the second ends of the drainage canals 580 through openings 582 disposed behind the retaining wall 522 and the flange 532, and thus outward to the exterior of the multi-component wall system 800. Angle 555 can be greater than about 90° so that water tends to flow away from the mounting bracket 542 and underlying support structure toward the openings 582.
FIGS. 20 and 21 illustrate yet another embodiment of a casing accessory 600 encompassing aspects of the present disclosure. The front component 20 is the same as that shown in FIGS. 1 and 3. However, the rear component 640 differs from the other embodiments of rear components shown in the drawings in that the rear component 640 includes a receiver 646 that has a plurality of drainage walls 668 and drainage canals 680 formed thereon. More specifically, the drainage walls 668 extend upward from the top wall 648 of the receiver 646 and are spaced apart from each other in order to form the drainage canals 680 there between. The angle 655 formed by the mounting bracket 642 and the top wall 648 is greater than the angle 53 formed by the retaining wall 22 and the spacer 24 so as to allow water or moisture to drain away from the mounting bracket 642 toward the drainage holes 26 formed in the spacer 24.
The components of the casing accessories of the present disclosure can be formed by methods known in the art, such as extruding, pultruding, stamping, cast forming and other methods, and can be made from materials such as aluminum, steel, other metals, polyvinyl chloride, coated PVC, pultruded fiber glass, and other materials that provide desired rigidity, flexibility, weight, corrosion resistance, compatibility with coatings, and fire resistance. In one aspect, the casing accessories encompassed by the present disclosure can be formed of one or more fire-resistant materials, such as metal or fiberglass, to impart enhanced resistance to fire to the multi-component wall system in which the casing accessory is used. The casing accessories of the present disclosure can be formed to varying lengths during manufacture or cut to the appropriate length at the installation site.
The casing accessories encompassed by the present disclosure can include spacers that include one or more of the structural and/or functional aspects of the receivers described herein, as well as receivers that serve as, either singly or in combination with one or more components of the casing accessory, spacers and can have width adjusters formed thereon or incorporated therein. Furthermore, two or more structures, such as one or more receivers and one or more spacers, can function as or cooperate to function as a spacer as set forth in the present disclosure. The spacers of the casing accessories encompasses by the present disclosure can be detachably connected to one or both of the front and rear components thereof, and, alternatively, be integrally formed with one of these such components.
The casing accessories of the present disclosure can include receivers with combinations of the characteristics described in detail above and alternatives thereto. While receivers with two walls and a slot formed there between, and two steps forming a seat have been described and shown in the drawings, other receiver configurations that are used to connect the front component to the rear component of the accessory are encompassed by the present disclosure. For example, the receiver can include one leg, or legs of varying widths, or various fastening mechanisms by which the spacer can be attached to the other component of the accessory.
Alternative configurations of the casing accessories of the present disclosure are contemplated and encompassed hereby. For example, rather than the spacer being formed in the front component and integrally formed with the retaining wall and the receiver integrally formed with the mounting bracket, the present disclosure encompasses casing accessories that include spacers and receivers that are switched, in that the spacer is integrally formed with the mounting bracket and the receiver is integrally formed with the retaining wall. Another alternative configuration includes a front component with spacer that is not continuous along its length. In this alternative, rather than strips extending along the entire length of the spacer, the strips can be intermittent along the length. In one aspect, the spacer can be integrally formed with only one of the rear component and the front component. In another aspect, the spacer can be manufactured separately from the mounting bracket and the retaining wall and then connected to both after manufacturing to provide an accessory with a channel with a desired width. In another aspect, the width adjusters of the casing accessories encompassed by the preset disclosure can be configured to be detached from the rest of the accessory or deformed, such as by folding or bending, to adjust the width of the spacer, thereby resulting in the adjustment of the channel width to the appropriate distance. In a further aspect, the present disclosure encompasses an adjustable component formed in the receiver such that adjustment of the receiver results in the adjustment of the adjustable channel width of the channel formed in the casing accessory. These and other alternative configurations are contemplated by the present disclosure.
It will be apparent to those skilled in the art that various modifications and variations can be made to the starter tracks set forth herein and are contemplated by the present disclosure.
