3.2 Trim Kit
3.2.1 Trim kit application
Trim kits are used to cosmetically cover wall openings when boxes are mounted semi-flush into the wall. The kit includes:
• Two top trim bands (shorter).
• Two side trim bands (longer).
• Four corner pieces.
Fig 4: Semi-flush trim kit
After mounting the box semi-flush to the wall, attach the trim per the following procedure:
1. The strips need to be cut before being attached. Carefully cut them to length using a hacksaw or sharp utility knife. Cut the strips approximately
1in. (25 mm) shorter than the box dimension. The box is 20-7/8 in. (530 mm) wide and 20-3/16 in. (512 mm) high.
2. Attach the strips one at the time. Peel off the adhesive tape release and center the strip on the box placing the edge of the strip against the box
surface, then press solidly to assure adhesion.
3. Each corner piece overlaps the trim strip slightly less than 3/4 in. (19 mm). Align the corner pieces tight to the box corner and attach with a drywall
or similar screw, suitable for the wall material. The screws are not supplied.
