Norton Closers 1601H689 Surface Mounted Door Closer

Product Description

The NORTON CLOSERS 1601H689 is a medium duty, surface mounted door closer with an adjustable hold open feature, supplied with sex nuts and finished in aluminum. It uses a rack and pinion hydraulic mechanism with valve-controlled adjustments to regulate closing speed and backcheck. The body is constructed from aluminum alloy, keeping the unit lightweight while maintaining structural integrity. This closer is installed by door hardware specialists or commercial contractors on standard swinging doors in commercial and light commercial applications where hold open functionality is required.

The 1601H689 is suited for interior and light commercial doors in facilities where traffic volume calls for a medium duty closer. The adjustable hold open arm allows the door to remain open at a set position, which is useful in warehouses, offices, schools, and healthcare settings. The sex nut fasteners are included for installations where through-bolt mounting is required rather than traditional wood or machine screw attachment.

Installation Notes

Surface mounted door closers of this type are typically installed by commercial door hardware technicians or general contractors following ANSI A156.4 standards. Shut off any access control or electric hold open systems connected to the door before beginning installation. Ensure the door frame and header are structurally sound and capable of supporting the closer and arm assembly. Follow the manufacturer template for hole placement and verify arm geometry matches the swing direction before final fastening.
