Suggested Accesories

Promaster Roof Vent Adapter for 14" x 14" Opening

Promaster Roof Air Conditioner Adapter
Patent Pending. Interior Framing Support System.

Adds support when installing a Maxxair Fan or an AC unit requiring a 14" x 14" opening with one of our Patent Pending Roof or AC 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 your air conditioner unit requires a larger hole please reach out to Kim 541-49O-4292

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".
