Lcn 4111-SCUSH Rh 689 Surface Door Closer Right-hand

Product Description

The LCN 4111-SCUSH RH 689 is a Grade 1 surface-mounted door closer designed for commercial and institutional door applications. It features a spring-loaded Cush-N-Stop arm that cushions the door at the end of its swing, reducing impact stress on the door frame and hardware. Configured for push-side parallel arm mounting, it delivers a 110-degree maximum swing arc and is adjustable from Size 1 through Size 5 to accommodate a range of door weights and widths. A full plastic cover protects the closer body, and the aluminum painted finish suits standard commercial door frames. Installation is performed by qualified door hardware or general contractors.

This closer is suited for commercial entryways, office corridors, institutional facilities, and other high-traffic door openings where controlled closing speed and stop-arm cushioning are required. The push-side parallel arm configuration is commonly used where overhead clearance is limited or where the closer body must be mounted on the push side of the door. The right-hand designation applies to doors with the hinge on the left when viewed from the push side. Size adjustability from 1 to 5 allows a single unit to serve a wide range of door sizes without replacing the closer body.

Installation Notes

Installation is typically performed by a licensed door hardware technician or commercial contractor following the manufacturer template and ANSI A156.4 standards for door closers. Secure the door in the open position and verify frame construction before drilling mounting holes. Follow the provided arm geometry template precisely, as incorrect arm positioning will affect closing force and door alignment. Adjust spring power only within the Size 1 to 5 range marked on the closer body.
