National Marker N223867 Heavy-duty Gate Hinge 3.5 in

Product Description

The NATIONAL MARKER N223867 is a heavy-duty gate hinge fabricated from hot-rolled steel for strength and durability in demanding applications. Measuring 3.5 inches by 3.5 inches, this hinge is engineered for narrow mounting surfaces where standard hinges may not fit. The tight-pin design allows installation in right-hand or left-hand configurations without modification. Suitable for full surface and half surface mounting, it gives installers flexibility across a wide range of door and enclosure setups. Supplied loose without screws, it is compatible with customer-supplied fasteners sized to the mounting material.

This hinge is intended for use on gates, barn doors, shed doors, storage bins, and tool boxes. Its compact 3.5-inch profile makes it a practical choice when mounting rails or stiles are narrow and larger hinges would overhang or interfere. The hot-rolled steel construction handles the repetitive stress and weather exposure common in agricultural, storage, and light industrial environments. Carpenters, general contractors, and maintenance technicians working on gate hardware and utility enclosures are the typical installers.

Key Features

• Hot-rolled steel construction for strength under load and impact

Compatibility

Designed as an OEM-style replacement or new-installation hinge for gates, barn doors, shed doors, storage bins, and tool boxes with narrow mounting surfaces requiring a 3.5-inch hinge.

Installation Notes

Install with appropriate fasteners for the door or gate material — screws, bolts, or lag hardware are not included and must be sourced separately. Ensure the mounting surface is flat and free of debris before positioning the hinge leaf. For outdoor applications, apply a corrosion-resistant finish or coating after installation to extend service life. No specialized tools are required beyond a drill and driver.
