The Delayed Action feature adjusts the time a door will remain open to facilitate ease of progress through the opening. This feature is valuable in health care facilities and public buildings that require door closers to momentarily stay open. Closing and latching speed controls are independently adjustable, and an adjustable backcheck feature helps prevent damage to the closer, door, and adjacent structures should the door be violently swung open due to wind or heavy pedestrian traffic.
All PR70 Closers are UL Listed and warranted for ten years. Parallel Arm Brackets and mounting hardware are included with each closer permitting universal installation for regular, top jamb or parallel arm applications. Optional accessories, such as Drop Plates and Hold Open Arms, are available for special installations.
