National Marker N128355 Galvanized Strap Hinge 3-1/8x8 in

Product Description

The NATIONAL MARKER N128355 is a heavy-duty galvanized strap hinge built for wide mounting surface applications including barn doors, shed doors, storage bins, tool boxes, and gates. Constructed from steel with a WeatherGuard galvanized coating, this hinge is engineered for long-term outdoor use where corrosion resistance is critical. The offset screw hole pattern adds structural strength and reduces the risk of wood splitting during installation. The tight pin design supports both right-hand and left-hand door applications, making it a versatile option for a range of field installations. Sold individually.

This strap hinge is suited for residential and light commercial exterior applications wherever a wide, flat mounting surface is present. Typical use cases include barn and shed doors, heavy-duty gate installations, tool box lids, and outdoor storage bin enclosures. The 8-inch strap length and 3-1/8-inch mounting width provide a broad bearing surface for doors subject to heavy use or significant load. The WeatherGuard coating makes it appropriate for direct exterior exposure without additional finishing. Installers should note that screws are not included with boxed loose-item packaging; visual pak versions are supplied with screws.

Compatibility

Corresponds to National catalog model No. 282BC and V282 series. Designed as a heavy-duty OEM-style replacement or new-installation strap hinge for barn doors, shed doors, gates, tool boxes, and outdoor storage bin applications requiring a wide mounting surface.

Installation Notes

Installation is typically performed by carpenters, general contractors, or experienced DIYers using standard hand tools. Power down any electrically operated door systems and ensure the door is secured before removing or installing hinges. Use fasteners appropriate for the substrate material and load requirements; consult local building codes for gate and barn door hardware specifications. Do not overtighten fasteners into wood substrates, as this can compromise holding strength even with offset hole geometry.
