MicroJambs come in 2 types: a “solid” type made of solid wood, micro-plywood or a composite; and a “hollow” type made either of extruded plastic or aluminum. Both types employ the same MicroJamb “system” consisting of parts that all attach to the MicroJamb quickly, and without the use of tools, via its unique, built-in, “strike, latch and stop” device. {In FIG. 3 it is that part of jamb “a” into which the male part of “d” (shown partially inserted) mates perfectly when fully inserted}
Said parts come in 4 categories:
- 1. Hollow Simulated Trim (MicroTrim) in a variety. of styles, both interior and exterior, made of extruded plastic.
- 2. “Trimless” Drywall Beads: one to eliminate all window and door trim (MicroTrimless) and made of extruded plastic {FIG. 3, part “d”}; the other to eliminate all base molding (MicroTrimlessBaseBead) made of either extruded plastic or aluminum. {FIG. 6 part “a”}
- 3. Stops, both interior and exterior, made of solid wood {FIG. 5, part “b”}, composites, extruded plastic and aluminum {FIG. 7, part “d”} and compliant materials such as Nylon and Neoprene.
- 4. Sill & Saddle Ramps {FIG. 7 parts “b” and “e”} are parts attached to the jamb to form sills and saddles where and when conditions exist that will not permit the use of “flared” trim to serve as the ramps.
- 5. A Combination FlaredTrim/Sill & Saddle Ramp
- {FIG. 8 part “a”}
- 6. Base Plugs: one to hide the gap between the finished flooring and wall (MicroBasePlug) {FIG. 6, part “g”}; the other (MicroBaseBumper) to hide the same gap but also to prevent the base of the drywall from being damaged by vacuum cleaner nozzels, chair legs, etc. {FIG. 8, part “a”}
All parts are attached to and detached from the MicroJamb via its unique, built-in, “strike, latch and stop” except for the MicroTrimlessBaseBead {FIG. 6 part “a”} which attaches to the sole plate of a wood-frame partition or wall, instead, without fasteners.
Other objects of the MicroJamb System are to:
- A. Eliminate the need for exterior caulking;
- B. Eliminate the need for drip caps;
- C. Eliminate the need to paint windows and doors;
- D. Reduce the cost of storing and transporting windows and doors (via their reduced size);
- E. Enable window and door trim to be installed quickly and easily, pre-cut, pre-mitred and without tools;
- F. Enable window and door jambs to be anchored with hidden fasteners {FIG. 3, part “g”};
- G. Enable the use of inexpensive exposed door hinges, when desired {FIG. 5, part “d”};
- H. Provide an improved seal against air and water infiltration by virtue of its 1-inch reduced width which enables MicroJambs to fit tightly between the drywall of wood-frame partitions {FIG. 3}, and between the drywall and sheathing of wood-frame exterior walls {FIG. 2}, whereas standard jambs invite air and water Infiltration (especially through exterior head jambs which, consequently, require drip caps).

DRAWINGS
FIG. 1, for comparison only, depicts a standard 5/4″×4½″ wood, window or door jamb {a} in an exterior wood-frame wall with interior wood trim {g} and exterior wood trim {f} and a standard drip cap {e}. Also shown is a double header {b}, plywood header filler {i}, sheathing {c}, siding {d}, and drywall {h}.
FIG. 2, in comparison, depicts a 5/4″×3½″ solid wood, window or door MicroJamb {a} in an exterior wood-frame wall with a MicroTrimless Drywall Bead {b} and (typical) Micro Exterior Trim {d}. Also shown is the drywall {c}. Note that no drip cap is needed. Also note that recesses in the front and rear edges of the MicroJamb enable it to be anchored (where necessary) with concealed fasteners (preferably screws) not shown.
FIG. 3 depicts a 5/4″×3½″ extruded plastic or aluminum MicroJamb {a} in an interior wood-frame partition, with a plastic MicroTrimlessDrywallBead {d} which is about to be installed via the built-in “strike, latch and stop”. Also shown are drywall {b}, jack stud {c}, screw port {e} (to attach jambs to each other), plastic U-shims {f} and anchoring wood screw {g}.
FIG. 4 depicts a 5/4″×3½″ reversible plastic or aluminum, window or door, MicroJamb to accommodate different size windows and doors.
FIG. 5 depicts a 5/4″×3½″ micro-laminated wood, interior door MicroJamb {a} with a wood door stop {b}, wood door {c}, door hinge {d} and jack stud {e}.
FIG. 6 depicts the MicroTrimlessDrywallBaseBead {a} which when combined with the use of the MicroTrimless DrywallBead (surrounding windows and doors) {FIG. 2, part “b”} enables interior walls to be completely trimless. An optional U-shaped MicroBasePlug {g} is used to conceal the gap which often exists between the finish floor and the wall. An optional J-shaped MicroBasePlugBumper {FIG. 9, part “a”} extends beyond the drywall to act as a (resilient) bumper to protect the drywall along its entire base. Also shown is subflooring {c}, finished floor {b}, sole plate {d}, wall stud {e}, & drywall {f}.
FIG. 7 depicts a 5/4″×3½″ extruded plastic or aluminum MicroJamb {a}. When combined with the (optional) Interior Saddle Ramp {b}, ExteriorSaddleRamp {e} and Door/WindowStop {d}, it becomes an exterior door saddle. Minus the InteriorSaddleRamp {b}, it becomes a window sill.
FIG. 8 {part “a”} depicts FlaredExteriorMicroTrim (used as an alternative to the ExteriorSaddleRamp used in FIG. 7, part “e”). FlaredMicroTrim serves both as exterior trim and as a Sill or Saddle Ramp. The 1:12 flare creates a 1:12 pitch to aid water-shedding when installed horizontally at the head and sill of windows and at the head and saddle of doors. And, as is true of all ExteriorMicroTrim, it has a flange to prevent air and water infiltration.
FIG. 9, {Part “a”} depicts the MicroBasePlugBumper.
