Titus Model TRM Surface Mounting Frame for Grilles & Lay-in Diffusers

For Plaster and Sheet Rock Ceilings
This “lay-in” style plaster frame makes installation of grilles, registers, diffusers, and other ceiling components in plaster and sheet rock ceiling as simple as inserting them in a standard T-bar type ceiling. The TRM is an aesthetically pleasing, inexpensive “access door” alternative for entry to the plenum space above the ceiling.

For typical applications the frame has adjustable fastening clips which adapt to a variety of plaster and sheet rock ceiling thicknesses. When heavy duty support is required the frame can be suspended with wire from the building structure.
