Product Description

The MCKINNEY HINGES TA231441232DNRP is a 4.5 x 4.5 inch square corner, standard weight, 5-knuckle ball bearing hinge designed for commercial architectural applications. It features a non-removable pin (NRP) for added security, a non-ferrous construction, and a satin stainless steel finish. The hinge weighs 1.1 pounds and is sold individually. It is intended for installation by commercial door hardware professionals and general contractors on commercial-grade door frames and panels requiring a durable, corrosion-resistant hinge solution.

This hinge is suited for commercial interior and select exterior door applications where a square corner profile is required. The satin stainless steel finish provides resistance to corrosion and blends with standard commercial hardware finishes. The non-removable pin design is appropriate for outswing door installations where pin security is a code or security requirement. Sold as an individual unit, with a case quantity of 48 for project or stock orders.

Installation Notes

Installation should be performed by a licensed door hardware technician or qualified commercial contractor in accordance with applicable building codes. Ensure the door and frame are properly prepared with a square corner mortise matching the hinge dimensions before installation. Secure all fasteners fully and verify door swing and clearance before returning the door to service. Do not substitute removable-pin hinges on outswing door applications where security or code compliance requires a non-removable pin.
