Honeywell ZD power close, spring open dampers feature solid extruded aluminum frame and blades and are riveted for rigidity with an integral low leakage seal. Powered by the same universal motor as the round ARD damper, these dampers install easily with just two wires and include a reliable, mechanical visual position indicator.
Note: When you go through the Check Out process there is an Order Comment box. Please specify which size ZD damper you want.
