3.4.2 Attaching the trim
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 1 in. or 25 mm shorter than the box dimension. The box is 15.83 in. or 402 mm wide and 19.83 in. or 490 mm high.
After mounting the box semi-flush to the wall, attach the trim by completing the following steps:
1. Attach the strips one at a time. Peel off the adhesive tape release and center the strip on the box placing the edge of the strip
against the box surface. Press solidly to ensure adhesion.
2. Each corner piece overlaps the trim strip slightly less than 3/4 in. or 19 mm. Align the corner pieces tight to the box corner and
attach with a drywall or a similar screw that is suitable for the wall material. The screws are not supplied.
