US Classification:
454333, 285406
Abstract:
A clamp assembly is provided for use in a duct system. The clamp assembly includes a clamp member including a base portion and first and second lateral portions. The first and second lateral portions extend less than the full circumferential length of the base portion. The clamp assembly may include a first member, a second member, and a hinge operatively coupling the first member to the second member. A damper access assembly includes an adapter, a damper access duct section, and an annular clamp member. A first flange of the adapter and a second flange of the duct section are configured to form a generally T-shaped joint between the adapter and the damper access duct section. The clamp member is configured to removably secure the adapter to the damper access duct section. The damper access duct section is configured to be removable relative to the damper enclosure and the ductwork.
