Description

The NORTON CLOSERS 7500690 is a heavy duty, adjustable surface mount door closer finished in dark bronze. It uses a rack and pinion mechanism with hydraulic valve controls to regulate door swing speed and backcheck, giving installers precise control over closing force and latch speed. The adjustable backcheck helps prevent door damage from hard opens. At 9.7 pounds and measuring 15.2 inches in length, 6.2 inches in width, and 3.8 inches in height, this is a substantial commercial-grade unit built for demanding door applications. Sex nuts are included for through-bolt installation on hollow metal and wood doors. Licensed door hardware installers and commercial finish carpenters are the typical trades handling this closer.

This closer is suited for commercial and institutional applications where a durable, adjustable surface mount solution is required. It is a non-handed design, meaning a single unit can be installed on left-hand or right-hand swing doors without modification. The dark bronze finish is a common specification on commercial storefronts, office entries, and institutional corridors where a consistent hardware finish is maintained across the door schedule. The included sex nuts allow through-bolt mounting where standard machine screw attachment is not sufficient for the door construction.

Installation Notes

Installation is typically performed by a licensed door hardware technician or commercial carpenter following the closer manufacturer template and applicable building code requirements. Power down any access control or electric strike on the door circuit before beginning work. Mount the closer body and arm bracket using the supplied sex nuts for through-bolt applications, ensuring fasteners are seated flush before adjusting valve settings. Adjust closing speed, latch speed, and backcheck valves only after the closer is fully mounted and the door is operating under normal conditions.
