National Marker N128157 Zinc Strap Hinge 3.125x8 in

Product Description

The NATIONAL MARKER N128157 is a heavy-duty strap hinge built for applications where wide mounting surfaces and long-term outdoor durability are required. Constructed from steel with a zinc-based WeatherGuard galvanized coating, this hinge resists corrosion and weathering in exposed outdoor environments. It measures 3.125 inches by 8 inches and is sold individually. The offset screw holes are engineered to distribute load and reduce the risk of wood splitting under repeated stress. A tight pin design allows installation for either right-hand or left-hand swing, making it adaptable without requiring a mirrored pair. This hinge is appropriate for installation by general contractors, carpenters, and maintenance professionals working on agricultural or light commercial structures.

This strap hinge is suited for residential and light commercial applications involving wide, heavy door panels and gate assemblies. Typical installations include barn doors, shed doors, storage bin lids, tool box lids, and gate frames where a longer hinge leaf is needed to spread load across a wider surface area. The galvanized WeatherGuard finish makes it appropriate for exterior use in high-moisture or weather-exposed environments. It corresponds to National catalog model numbers 282BC and V282 series. This item ships as a single hinge without screws.

Installation Notes

Installation is typically performed by carpenters, general contractors, or maintenance technicians using standard hand tools. Power down or secure any gate or door panel before removing an existing hinge to prevent uncontrolled movement. Fasteners are not included and should be selected based on the substrate material and load requirements. For exterior wood applications, use corrosion-resistant screws compatible with treated lumber to maintain the longevity of the WeatherGuard finish.
