National Marker N273888 Weldable Door Hinge 2 in Square

Product Description

The NATIONAL MARKER N273888 is a 2-inch square, plain steel weldable door hinge designed for surface mounting on metal doors and frames. This heavy-duty hinge features a nonswaged body and a nonremovable, tight-fit pin, making it well suited for secure, permanent installations. Fabricated from cold-rolled steel with a plain steel finish, it is intended for welded application rather than screw or bolt mounting. Metalworkers, millwrights, and maintenance technicians typically specify this hinge when a flush-mount, weld-on solution is required for metal enclosures, gates, or access panels.

The N273888 is used in light industrial and commercial applications where a durable, weld-on hinge is preferred over surface-fastened hardware. Its nonswaged design allows full surface contact with the mounting substrate, which is critical for strong weld adhesion. The tight, nonremovable pin provides added security in applications where hinge tamper-resistance or pin retention matters, such as utility enclosures, equipment access doors, and fabricated metal assemblies.

Key Features

• Nonswaged body enables full surface contact for reliable weld-on installation
• Nonremovable pin adds security and prevents accidental disassembly
• Tight-fit pin construction for more secure, stable hinge action
• Cold-rolled steel hinge body and steel pin for consistent material properties
• Plain steel finish suitable for painting or coating after installation
• Compact 2-inch square profile fits tight-clearance door and panel applications

Compatibility

Designed as a weld-on surface-mount hinge for metal doors, gates, enclosures, and fabricated panels requiring a nonremovable-pin, nonswaged hinge solution.

Installation Notes

Installation is performed by qualified welders or metalworkers using appropriate MIG, TIG, or stick welding equipment. Ensure the mounting surface is clean, free of coatings, and properly fixtured before tacking the hinge in place. Verify door alignment before completing full weld passes to avoid binding. Allow welds to cool fully before cycling the hinge or applying finish coatings.
