TECHNICAL FIELD
The present invention relates to electrical cut-in boxes specifically for old work cut-in boxes for installing new switches and plugs in dwelling units or commercial buildings.
BACKGROUND
Old cut in boxes are more expensive to make and are limited to their specific design, if there is a shortage then there are no good substitutes. Some of the old work cut-in boxes (metal) currently in use come with external clips that have to be purchased separately to be installed and one does not work with out the other. The plastic cut-in boxes have to be purchased as a single unit and the cost is greater than basic nail on boxes. Here are a list of old cut in box types for reference:
1. Hubbell Raco 8977 Grip-loc Old work switch box straps and support for specific metal boxes that have front tabs to prevent the box from falling inside the wall opening.
2. Raco 969 box support clip also for a specific metal cut in box.
3. Hubbell-Raco 506 Switch box 3×2 inch deep Metal box.
4. Raco 7887rac 2¼ inch Old work single gan cable box.
5. Carlon Ceiling 2.75 inch Round Old Work box 18 cu.
6. Carlon B114R-UPC Lamson home products number 1G Old.
7. Raco 523 2½D bx switch box with Grips.
8. Pass and Seymour Slater switch outlet box 18 cu in one gang, cut in electrical box.
9. Steelcty 820-D-2 Switch box supports 2 pair.
10. Raco 545 3×2 Old work box w/NMC Clamps.
11. Q-Clip single gang Cut-In box holders.
12. Steel City Old Work-Swing-Ear Old work Swing Ears with self threading screws, Manufacture Thomas & Betts Item #12651.
All of the above listed items have to be used with a manufactured box with the front top and bottom tabs already integrated into the box for function.
SUMMARY OF THE EMBODIMENTS
The New work to Old work electrical box clip can be made of a rigid or malleable materials of multicolor or multi shaped cross sections and is used to hold a modified nail on electrical box, (or can be manufactured into a box), in drywall for the installation of electrical switches, receptacles or to be used as a junction box. The New work to Old work clips can be used on round, rectangular and square types of electrical boxes; rectangular single gang, two gang, three gang or four gang just by adding extra Box Clips. The New work to Old work electrical box clip can be made as a stand alone Old work electrical box and the dimensions of the box clips can be installed in any size drywall, example; ⅜'s inch drywall, ½ inch drywall and ⅝'s drywall.

DETAIL DESCRIPTION OF DRAWINGS
FIG. 1 dimension can be manufactured to fit any thickness of drywall ⅜″, ½″ or ⅝″ etc.
For clear understand I will describe box clips designed for ⅝s inch drywall, these measurements will be able to be transferred to work with any size drywall.

FIG. 1 measurement for #102 are from first 90 degree turn to second 90 degree turn are 9/16 of an inch, for snug fit that holds in drywall. FIG. 1 measurement for #104 are from second 90 degree turn to third 90 90 degree turn are 13/4 inch from outside to outside. FIG. 1 measurements for #106 are a saddle bend (or a flattened hammered area about a ¼ inch) to be used to lock the box clip into place for added tight fit and starts about a ¼ inch up from the second 90 degree turn to mirrored on the opposite hook. FIG. 1 measurements for #108 are the thickness of the malleable round wire type metal at 3/32s of an inch.
FIG. 2 is a side view of the box clips with the same exact measurements of FIG. 1.
