1/2'' Shaft Loc Quadrant Set (For Dampers up to 30'')

“Shaft Loc” Quadrants are stamped of heavy gauge steel and clearly indicate the position of the damper.
The quadrant handle (available for either 1/2” square or round shafts) is unique in that it locks the shaft of the damper to it by means of a powerful friction holding device strong enough to cut into the damper shaft eliminating damper rattle. The shaft is easily locked with 1/2” open end wrench. Available for square or round ducts.
