The RQD is designed for round ductwork systems where straightforward manual air balancing is required. The Quick Click quadrant handle allows installers and commissioning technicians to quickly set and lock the blade position without tools, making it practical for both new construction and retrofit balancing work. It is well suited for branch takeoffs, terminal unit connections, and other points in commercial and institutional HVAC systems where airflow needs to be balanced and held at a fixed position.
