• Cut the perimeter channels to length to fit the bottom top
and both sides of this opening (Illus. A). These may be cut
square or mitered. Apply two
1
/
4
” beads of sealant on
underside of channels horizontally
1
/
2
” from both sides.
Screw channels to the bottom and two sides of opening
using the holes provided. Use two screws to fasten each
end. If you cut off the predrilled holes when trimming the
length, simply drill new ones at each end of the cut piece.
Paint the screw heads white to reduce visibility.
