RRD Series These low-cost retrofit dampers make it easy to quickly add zoning to an existing duct system. Unlike a traditional damper which is built into a shell, the RRD dampers are designed to slip into a hole cut into the existing ductwork. The Rheem Retro Damper is the perfect alternative to expensive pneumatic systems that require special plastic tubing and pumps. This damper uses standard thermostat wire and will work with most 24V zone control panels.
