TRUaire SD1A Saddle Mounted Spiral Diffusers Aluminum Finish

Spiral SD1A 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
  • No damper or scoop
  • 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.
