Spiral SD1W 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.
White powder-coat finish
Single 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.
