7 CEILING IFFUSER OPTIONS AN ACCESSORIES Mounting Frames MOELS: FS (Steel), FA (Aluminum) rywall/plaster Frame The F Series are for mounting in finished drywall or plaster ceilings to accept any standard lay-in type grille, register, diffuser or other ceiling component. Installation of the air outlet is as simple as inserting them in a standard lay-in T-Bar type ceiling system. The F Series simplifies and reduces installation time compared with surface mount type diffusers. This is especially true where flexible duct is utilized. A major benefit is that the F Series allows access to the ceiling plenum space above for maintenance purposes without the need for separate access doors. The finished appearance is professional and aesthetically pleasing. Standard Finish: AW Appliance White baked enamel. Other finishes are available. Model FS is installed quickly and easily using adjustable fastening angle brackets which adapt to various ceiling thicknesses. Frames are roll-formed corrosion-resistant steel with staked and mitered corners. IMPERIAL METRIC MOULES MOULES Imperial S.I. S.I.
