About this detail

An exposed round supply diffuser features a perforated duct diffuser with an end cap and a center line equal to the main duct in the room unless otherwise indicated. A radial opposed blade damper is installed with clearance minimized as required. A 90-degree tee takeoff connects the run-out duct to a square or rectangular return grille sized per plans. Pendant mount lights are positioned with upper and lower edges aligned with the diffusers and grilles. A six-inch clearance is maintained for plumbing pipes and racks. All exposed ductwork, diffusers, and grilles are primed and painted.
