Ring dampers are installed in-line within duct runs to regulate or shut off airflow to individual zones or registers. This assembly provides manual or system-controlled airflow adjustment at the point of distribution. Licensed HVAC technicians and sheet metal contractors install this type of damper during new construction, renovation, or service work on forced-air ventilation and comfort-cooling systems.\u003c\/p\u003e\u003cp\u003eThis ring damper assembly is suited for residential and light commercial forced-air HVAC applications where 10-inch round duct is used. It is typically installed at branch takeoffs, trunk-to-branch transitions, or directly behind register boots to balance airflow across multiple zones.
