Frames
Plaster frames are available to provide a positive-dimensioned ceiling or wall opening
for the diffuser or grille.
Frames for S Series diffusers are furnished with formed bridge spacers to maintain a
uniform, rigid opening during installation. The duct collar is fastened to the frame.
See specific S Series for frame dimensions and installation details.
Damper
Single-leaf dampers are furnished in each slot opening throughout the entire diffuser
length when specified. Dampers are fastened to the margin and are spring-loaded
to hold their setting at all duct pressures. Multiple dampers are furnished for grille
lengths over 24 inches.
Dampers are part of the S Series and are not specified separately.
