Linear and Slot Diffusers
44
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.
90-degree mitered corners are available as factory-fabricated sections. Precise
factory cutting and assembly reduces field fabrication time and assures proper
fit. Mitered corner sections are furnished in one piece, with pattern deflectors and
dampers in the dimensions as indicated. Corner sections butt to adjacent straight
sections, which are spliced together with aligning keys.
Mitered corners are furnished in style #4 (with pattern controller and damper). When
viewed from the room side, the mitered corner section appears identical to the butting
straight sections.
Plaster-frame mitered corners can be specified with the outlet mitered corner.
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.
