CRL Overhead Concealed Door Closers
provide an aesthetically appealing way to close a door. In situations where a closer is needed but concealment in the frame header is required or desired, the Norton® 7900 Closer is the ideal solution for door control. Once installed, only the solid one-piece arm is visible when the door is open; therefore, this unit provides a high degree of vandal resistance. When the door is closed, the closer, arm and slide track are fully concealed.
Norton® 7900 Overhead Closers are best suited for high-profile applications, such as office buildings or conference centers. This heavy-duty, durable closer package includes a steel track, steel slider, polymer slider pads, and dress plates. The steel track and slider offer additional strength to the unit, while the polymer pads provide quiet operation and easy assembly. Standard features include rack and pinion operation, adjustable sweep and latch, plus adjustable backcheck cushioning and positioning.
All Norton® Series 7900 Closers are packed one to a box, with an arm and a slide track, one hex key for control valve adjustment (and hold open tension adjustment), one hex key for arm to track attachment, and one hex key for anchoring cushion stop in track. Installation instructions and both wood screws and metal screws for mounting are included.
