TRUaire / Spiral Diffusers with Saddle

SD2A Saddle Mounted Spiral Diffusers Aluminum Finish

spiral duct
aluminum

rectangle

Spiral SD2A 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
  • Double deflection configuration
  • No damper or scoop
  • Saddle curved to fit duct radius
  • Adjustable bars on grille face

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

TRUaire grilles ship from their CA and TX warehouses. Large quantities are typically available.
