CRL Overhead Concealed Door Closers provide an aesthetically clean, vandal-resistant solution for commercial doors where concealment in the frame header is required. The Norton® 7900 overhead concealed closer (SKU: 7900BF1RA) leaves only the solid one-piece arm visible when the door is open; when closed, the closer, arm and slide track are fully concealed—ideal for office buildings, conference centers, and other high-profile venues. Norton® 7900 overhead concealed closers are heavy-duty and durable, featuring a steel track and slider with polymer slider pads for quiet operation and easier installation. Standard commercial door closer features include rack-and-pinion operation, adjustable sweep and latch, adjustable backcheck cushioning and positioning, multi-size adjustable spring power, and an adjustable hold-open option—making it a reliable overhead concealed closer for commercial doors requiring Grade 1 performance and ADA-compliant opening forces. Packaging Information: All Norton® Series 7900 closers are packaged one per box and include an arm and slide track, three hex keys (control valve and hold-open tension adjustment, arm-to-track attachment, and anchoring cushion stop), installation instructions, and both wood and metal screws for mounting.
