发明名称 DAMPER ACCESS ASSEMBLY
摘要 A damper access assembly includes an adapter and a removable damper access duct section for use in a ventilation duct system to access a damper. The adapter includes a radially outwardly directed flange. Each of the ends of the damper access duct section includes a radially outwardly directed flange. The flange of the adapter is configured to be operatively and releasably coupled to one of the flanges of the damper access duct section. The other second flange at the other end of the damper access duct section is configured to be operatively and releasably coupled to the ductwork. A technician may release the damper access duct section from the adapter and from the ductwork and remove the damper access duct section to access the damper. The damper access assembly may include one or more clamps that cooperate with the flanges of the adapter and the removable access duct section.
