Duro Dyne’s Cable Operated Damper (COD) Kits are available in both gear-driven and push/pull configurations, with cable lengths ranging up to 50 feet to accommodate a variety of jobsite conditions. These versatile kits allow for connections to ¼", 3/8” square and 3/8”, ½" round damper bearings and offer select mounting options like ceiling cup kits or drop ceiling brackets for a clean, professional finish.  

Whether used in round or rectangular ductwork, COD Kits ensure easy adjustment of damper blade position via a simple cable interface—just push, pull, or turn. Once the desired airflow is set, the mechanism is secured with a set screw or driver, locking the blade in place. Accessories like PVC ceiling caps and gear/bracket combos allow contractors to customize each install for performance and aesthetics.  

COD Kits exemplify Duro Dyne’s commitment to innovation and installer-focused design. With a broad range of kit types and parts, HVAC professionals can confidently standardize on a proven solution that’s as versatile as it is dependable.
