Norton Closers 8501H690 Surface Mount Door Closer

Product Description

The NORTON CLOSERS 8501H690 is a surface mount door closer with adjustable hold-open functionality, a full cover, and a dark bronze finish. It uses a rack and pinion mechanism with hydraulic valve control to regulate door swing speed and backcheck. The unit is designed for commercial door applications where controlled closing speed and hold-open positioning are required. Licensed door hardware technicians and commercial contractors typically specify and install this closer. Key attributes include adjustable closing and latching speed, valve-controlled backcheck, and an aluminum alloy body construction.

This closer is suited for commercial and institutional applications where surface mounting is required and hold-open capability is a code or operational requirement. The full cover assembly protects the internal mechanism from dust and tampering. The dark bronze finish integrates with common commercial door hardware finishes. Installation is performed at the door head on either the push or pull side depending on the arm configuration selected.

Installation Notes

Installation is performed by a licensed door hardware technician or commercial contractor. Before mounting, verify door weight, width, and applicable fire-rating requirements, as closer size selection must comply with ANSI and local building codes. Power is not required for this mechanical closer, but all hydraulic speed adjustments should be made with the door in operation using a flat-blade screwdriver on the valve screws. Do not over-tighten valve adjustments, as doing so can damage internal seals.
