High Quality: Our Damper & Sleeves are made from Galvanized Steel. All sleeves fabricated from galvanized steel meeting ASTM-A-653-96 standards, by the latest edition of SMACNA gauges and construction standards. It can also be used for wind protection. Designed for use in AC, dryer vent, exhaust, extractor, heating systems, fans, vents, and other residential, commercial, and industrial HVAC applications.

Duct Installation Tips and Trick: To install Damper Sleeves, you simply slide the sleeve into the item you are attaching to and fasted with sheet metal screws, and conceal the seam with duct tape. We do recommend that you seal around all sheet metal to sheet metal connections with a duct sealant to prevent air leakage, and increase the efficiency of your HVAC system. This damper does not have a 100% seal it's used for air balancing, not air termination.

Balancing Airflow: Balancing dampers are simply manual dampers encased in a galvanized sheet metal sleeve. Each branch should have a balancing damper installed. That way, it's possible to regulate the airflow by adjusting the position of the damper. They should be located in areas that are easily accessible for adjustment. The ductwork regulates the flow of air and redirects it to specific places of a house.
