About this detail

An insulated plenum connects to a square ceiling diffuser neck and is secured with screws. A forty percent free area perforated plate spans across the plenum with the top of the plate aligned at the centerline of the inlet. Flexible ducting attaches to the plenum via clamps and runs back to a supply duct equipped with a spin-in fitting and volume damper. A one-inch wide strap hanger bolts around the duct and extends up to the structure, adjusted to relieve strain from the diffusers. The diffuser is set for horizontal throw and can be adjusted for one, two, three, or four-way throws.
