Description
1/2" round Shaft loc quadrant is stamped of heavy gauge steel, and clearly indicates the position of the damper. The quadrant handle is unique in that it locks the shaft of the damper to it by means of a strong friction holding device powerful enough to cut into the damper shaft, alleviating unwanted damper rattle. The shaft is easily locked with a 1/2 open end wrench.
Works with dampers up to 30".
