The Manual Adjustable Round Dampers are single blade round dampers with a hand adjustable self-locking quadrant. These dampers are the simple solution for controlling air volume in any duct system. These dampers can be used as “hand” dampers as referred to in ACCA Manual ZR to further control by-pass air. The different models are simply for application for in-line duct locations, take-off collars or insertion into existing round metal ducts.
