S Series Mitered Corner

Mitered Corners

  • 90-degree mitered corners are available as factory-fabricated section. Precise factory cutting and assembly reduces field fabrication time and assures proper fit. Corner sections are furnished and blanked off. 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.

NOTE: DRAWING REQUIRED when ordering linear or slot diffusers with mitered corners.

  • 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.
