PermaFrame for Hard/Gypsum Ceilings

The PermaFrame provides a support structure and room-side finish trim in one piece. It is supplied 
with predrilled mounting holes located on the vertical flanges that are used to easily level and anchor 
the frame to customer-supplied studs above the ceiling structure. Manufactured of 18-gauge cold-
rolled steel or stainless steel, the welding on all exposed corners guarantees a smooth, cleanable 
surface. White powder coat paint is supplied as standard finish. The PermaFrame is ordered 
separately from the AstroHood

 unit.
