UNIVERSAL STANDOFF REGULATORS

The Universal Economy Standoff Regulator from Duro Dyne is a hand operated elevated regulator designed for use with 1/4” or 3/8” 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. It is offered in four standoff heights: 1’’, 1-1/2’’, 2’’ & 3’’. 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 UESO to work for multiple damper
fitting applications including Hetos.

The Duro-Twist is a hand operated elevated regulator designed for use with square rod on both square and round externally insulated duct.
It is offered in four standoff heights: 1’’, 1-1/2’’, 2’’ & 3’’. The Duro-Twist is engineered with a strong friction resistance so it stays set
without any need to lock it in place. The high visibility yellow handle allows it to be easily found in the field on wrapped duct. The handle
position illustrates damper blade position on the outside of the ductwork.
