With its unique locking features, this damper regulator locking extension provides significantly increased labor and time savings, offering a quick and easy installation that does not require the use of a small set screw and enables last-minute field changes to be completed in a matter of minutes, said the company. With an additional locking feature, the Kwiki locking extension provides enhanced security to any damper regulator application. First the barrel is tightened, locking the damper blade to the side of the damper, and then the wing nut is also tightened, ensuring that the damper blade remains in place. Extending two inches from the damper, the extension also enables the duct system to utilize external insulation with a higher R-value, improving the energy efficiency of the building and enabling building owners to achieve decreased energy costs. The Kwiki locking extension will replace the Kwiki non-locking extension.
