REGULATOR STANDOFF 3/8inx1/2in

The Universal Economy Standoff Regulator from Duro Dyne is a hand operated elevated regulator designed for use with 1/4 in or 3/8 in square rod on externally insulated duct. The unique 10 degree foot, allows the same regulator to be used on both square or round ductwork, alleviating the need to stock multiple regulators. The handle is locked in place with a heavy duty high torque stamped wing nut and clearly shows damper position with embossed designations for open and closed. Reinforcing gussets in four locations add to the rigidity of this regulator. An optional score and Heto Notch allows the ESO to work for multiple damper fitting applications including Hetos.
