This kit is designed to control and regulate airflow in HVAC (Heating, Ventilation, and Air Conditioning) systems.

Typically composed of a sturdy quadrant (dial section) and a damper rod, it enables precise airflow adjustment to ensure proper air distribution.

Key features include smooth handle operation, quick adjustment and locking via wing nuts, and a frame marked with a calibrated dial for accurate damper positioning.

Suitable for use with both square and round ducts.
