Linear and Slot Diffusers

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. They are

face-operated with a removable operator. Multiple dampers are furnished

for grille lengths over 24 inches.

Dampers are part of the S Series and are not specified separately.
