National Mfg N273-888 2 Inch Plain Steel Weldable Door Hinge

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N273-888 is a 2-inch plain steel door hinge engineered for surface application by welding. Manufactured from cold rolled steel, this non-swaged hinge features a full mortise design with five knuckles and a tight pin for increased security in demanding installations. The weldable construction makes it suitable for fabrication environments where mechanical fasteners are not preferred. It is sold in a boxed loose pack of 10 units per package, making it a practical choice for contractors and tradespeople working on multiple openings.

This hinge is intended for use in commercial and industrial door applications where a weldable, non-swaged hinge is required. The full mortise design fits flush within the door and frame, providing a clean finished appearance. The tight pin configuration reduces play and improves security, making it appropriate for gates, utility doors, access panels, and similar high-cycle or security-sensitive applications. Installation is typically performed by ironworkers, general contractors, or door and hardware specialists during rough-in or finish work.

Installation Notes

Installation of weldable hinges requires proper welding equipment and should be performed by a qualified fabricator or door hardware installer. Ensure the door and frame are properly aligned and secured before tacking or finishing welds. Follow applicable building codes and manufacturer guidelines for door hinge placement and spacing. Allow all welds to cool fully before testing door operation or applying finish treatments.
