5.7 Step 3. Trim Kit Application (optional)
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.
5.7.1 Trim Application
After the back box is mounted to the wall, attach the trim in accordance with the following procedure:
1. Hold the top strip against the top of the back box.
2. Centered the strip on the box width, and mark the end locations (the top bands are approximately 1" (25 mm) shorter than the
box width). Peel off the adhesive tape release, align it with the marks and press down to assure adhesion.
3. Place the second top strip beneath the back box and repeat step 2.
4. The side bands are sized for the 3-bay box, they must be re-sized for use with 1 and 2 bay boxes.
- For use with a 3-bay box: align, mark, and attach as was done for the top and bottom bands.
- For use with a 1-bay or 2-bay boxes, cut the bands approximately 1" (25mm) shorter than the box height (1-bay boxes are 22" (559
mm) high, 2-bay boxes are 40" (1016 mm) high). Carefully cut them to length using a hacksaw or sharp utility knife.
5. Attach the cut bands using the same procedure as the top and bottom bands.
6. Each corner piece overlaps the trim strip slightly less than 3/4" (19mm). Align the corner pieces tight to the box corner and attach
with a drywall or similar screw, suitable for the wall material (screws are not supplied).
