Description

Patent Pending. Interior Framing Support System.

Adds support when installing a vent fan requiring a 14" x 14" opening with one of our Patent Pending Vent Fan Adapters for the Promaster. They are made of Expanded PVC material. Much easier to work with than wood. They also provide a backing for the screws that hold up the vent interior bezel.

Match the Bay to the position of the outside adapter that you are placing on the roof.

If you have Super High Roof Promaster, please let us know.

The strips come unassembled. The strips are glued in with 3M Window Weld or Sikaflex 221. The strips should be spaced out from the hole approximately 1/4".
