CRL Cast Iron Closers have long been considered the industry’s most durable. The CRL PR90 Grade 1 Adjustable Spring Power Surface Mounted Door Closer is recommended for high traffic public buildings such as hospitals, airports, and shopping centers, to meet both A.D.A. accessibility requirements, and provide durability and maintenance-free service. Closing and latching speed controls are independently adjustable, and an adjustable backcheck feature helps prevent damage to the closer, door, and adjacent surface should the door be violently swung open due to wind or heavy pedestrian traffic.
