This 7-inch adjustable damper kit provides manual airflow control for compatible round HVAC ductwork and fittings. The round damper blade can be positioned to regulate airflow through the duct, helping balance supply-air, return-air, and ventilation systems.
Constructed from galvanized steel, the kit includes the damper blade and adjustment hardware required for field installation. It is suitable for residential and commercial HVAC applications where manual volume control is needed.
Sizing Note: The 7-inch measurement identifies the nominal diameter of the compatible round duct or fitting. Confirm the required duct size before ordering.
