Norton Closers 8501H689 Surface Mount Door Closer

Product Description

The NORTON CLOSERS 8501H689 is a surface mount door closer with adjustable hold-open functionality, designed for commercial and light-industrial door applications. The unit ships with a full cover and sex nuts for secure mounting. Built on a rack and pinion mechanism with hydraulic valve-controlled backcheck, it delivers consistent closing speed and reliable door control. The aluminum finish body keeps the unit lightweight without sacrificing durability. At 8.5 pounds and measuring 15.2 inches in length, 6.2 inches in width, and 3.8 inches in height, it fits standard commercial door frames without extensive modification.

This door closer is suited for commercial entryways, office corridors, and institutional facilities where controlled door swing and hold-open capability are required. The adjustable hold-open feature allows the door to remain open at a set position, useful in high-traffic areas or for ADA-compliant access routes. Licensed door hardware professionals and general contractors typically handle installation on hollow metal or wood doors with standard closer preparation.
