Norton Closers 8301689 Surface Mount Door Closer

Product Description

The NORTON CLOSERS 8301689 is an adjustable surface mount door closer featuring a slim line cover and sex nut mounting hardware in an aluminum finish. It uses a rack and pinion mechanism with hydraulic valve-controlled backcheck to regulate door swing speed and closing force. The aluminum alloy body keeps weight low while maintaining durability in commercial door applications. Licensed door hardware technicians and commercial contractors install this closer as part of a complete door control assembly on standard hinged door openings.

This closer is suited for commercial and light-institutional settings where a surface mount solution is required. The non-handed design simplifies installation on both left-hand and right-hand doors without the need for separate handing procedures. Adjustable backcheck and independent sweep and latch speed valves allow the installer to fine-tune closing performance to meet door traffic and code requirements on site.

Installation Notes

Installation is performed by a licensed door hardware technician or commercial contractor. Disconnect or secure the door in open position before beginning mounting to prevent uncontrolled swing during work. Follow the door manufacturer and ANSI A156.4 guidelines for fastener placement and arm geometry. After mounting, adjust sweep, latch, and backcheck valves incrementally and cycle the door multiple times to verify closing force and speed before returning the door to service.
