Norton Closers 7500689 Heavy Duty Surface Mount Door Closer

Product Description

The NORTON CLOSERS 7500689 is an adjustable heavy duty surface mount door closer finished in aluminum and supplied with sex nuts for secure mounting. Built around a rack and pinion mechanism with hydraulic valve control, this closer delivers consistent sweep and latch speed across a wide range of door weights and traffic levels. The adjustable backcheck feature helps protect the door and frame from impact damage during hard openings. Licensed contractors and door hardware installers specify this closer for commercial and institutional applications where durability and repeatable performance are required.

This closer is intended for surface mount installation on heavy duty commercial doors. The aluminum finish suits interior and light exterior applications where a clean, low-profile appearance is expected. The included sex nuts allow for solid, pull-through mounting into hollow metal and wood doors without the need for through-bolts. Adjustable sweep, latch, and backcheck valves let the installer dial in closing performance to match door weight, frequency of use, and code compliance requirements.

Installation Notes

Installation is typically performed by a licensed door hardware technician or commercial general contractor. Shut the door and secure it open before drilling or fastening to prevent movement during layout. Follow ANSI and local building code requirements for closer placement and required closing force on accessible routes covered under ADA guidelines. Do not over-tighten the valve adjustment screws, as doing so can damage internal seals and void the closer warranty.
