About this detail

A ceiling diffuser is integrated into a lay-in T-bar ceiling and connected to a supply duct using flexible ductwork and a five-gore sheet metal elbow. The five-gore elbow requires a centerline radius of one and a half times the duct diameter, or a short-radius rigid metal elbow where space is restricted, secured with a minimum of four sheet metal screws. A one-inch wide strap hanger bolts around the duct and extends upward to the structure, adjusted to relieve strain from the diffusers. A spin-in fitting with a volume damper connects the flexible duct to the main supply duct, with clamps securing the connections. The diffuser is set for horizontal throw and adjusted for one, two, three, or four-way throws depending on position.
