Our interior trim kit ships flat and assembly is required.
nail gun (you may alternately use finish nails or screws)
drill with small diameter bit to drill pilot holes if nail gun is not available
STEP 1 — ASSEMBLE INTERIOR TRIM KIT
Lay pieces of the trim kit out, so you can get the feel for how it goes together. Be sure the "picture frame" is laying with the recess up. You will see that the two shorter pieces go in the upper and lower position and the longer pieces go in the left and right position. The recesses in the shorter pieces align with the ends of the longer pieces.
Apply wood glue to the recesses of the shorter pieces and carefully align them with the longer pieces. Nail or screw into place.
If you do not have a finish nail gun, you will need to drill pilot holes and fasten with finish nails or small diameter screws.
You can now nail or screw the picture frame into the box.
Flip it over and your assembled trim kit should look like this.
STEP 2 — INSTALL INTERIOR TRIM KIT
Measure each side of the return of the interior foundation wall and mark the corresponding corners of the trim box.
Using a circular saw, ideally a track saw, carefully trim the jamb to fit the reveal.
Fasten the trim box in a suitable fashion.
We recommend finishing the trim with stain, or primer and paint.
