TRUaire SD1A-S Saddle Mounted Spiral Diffusers With Scoop Aluminum Finish

Spiral SD1A-S Duct Diffusers were born of the rustic exposed ceiling era in architectural design. Wherever air needs to leave ductwork and enter the conditioned space a hole is cut in the duct. A register is then attached for directional air control and aesthetics. The saddle type diffuser is available in either single deflection or double deflection blade configurations.

  • Unfinished aluminum appearance
  • Single deflection configuration
  • Includes adjustable air scoop
  • No damper
  • Saddle curved to fit duct radius
  • Adjustable bars on grille face

Note that LIST SIZE is the size of the duct opening.  See submittal sheet for actual grille dimensions.
