Norton Closers 1601689 Surface Mounted Door Closer

Product Description

The NORTON CLOSERS 1601689 is an adjustable, medium-duty surface mounted door closer finished in aluminum. It uses a rack and pinion mechanism with hydraulic valve controls to regulate door swing speed, backcheck, and latch action. Sex nuts are included for straightforward mounting to door and frame assemblies. At 12.1 inches long, 5 inches wide, and 3.7 inches tall, it fits standard commercial and light commercial door openings without requiring specialty hardware. Licensed door hardware technicians and commercial contractors are the typical installers for this type of unit.

This closer is suited for medium-duty applications in commercial and institutional settings where consistent, controlled door closing is required. Typical installations include office entry doors, corridor doors, and light-traffic access points. The adjustable valve design allows the technician to fine-tune closing speed and backcheck force on-site to match door weight and traffic patterns. The aluminum finish blends with standard commercial door hardware and resists corrosion in interior environments.

Installation Notes

Installation is performed by a licensed door hardware technician or commercial contractor. Ensure the door is held open or secured before mounting to prevent movement during installation. Follow ANSI A156.4 standards for door closer installation and adjust valves only with the door in the fully closed position to set accurate closing force. Do not over-tighten the sex nuts, as this can distort the mounting plate and affect closer alignment.
