NOTE:
If you have the 2X2 configuration, you will not use the sliders (front-to-back bars).
For a Lipless Closure System (OPT1L, OPT3L) cut a plywood backer board and ceiling
media (drywall, ceiling tile) 3/8” smaller than the hole cut out in the ceiling.
Glue or screw the ceiling media to the backer board. Add two 1” x 4” wood supports
across the width of the closure frame. Screw through the wood supports into the
plywood backer board.
NOTE:
Leave enough play in the screws to slide the ceiling closure for precise alignment of the
panel. Prep the ceiling closure panel by painting it to match the existing ceiling.
If you have a Lipped Closure System (OPT1, OPT3), fit your ceiling tile or other ceiling
media within the closure frame.
