National Mfg N128-272 5 Inch Galvanized Heavy Strap Hinge

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N128-272 is a 5-inch galvanized heavy strap hinge built for wide-surface mounting applications where strength and weather resistance are required. The hinge features a brass pin that allows use in either right-hand or left-hand configurations without modification. Offset screw holes are engineered into the design to distribute load and reduce the risk of wood splitting during installation. This is a heavy-duty unit suited for exterior and agricultural hardware applications installed by general contractors, carpenters, and experienced DIYers.

The N128-272 is designed for applications that demand a wide mounting footprint and durable construction. Typical use cases include barn doors, shed doors, storage bins, tool boxes, and gates. The galvanized finish provides corrosion resistance in outdoor and high-humidity environments. The hinge ships boxed loose and is sold in a package quantity of 10 units, making it practical for new construction or replacement projects requiring multiple hinges per job.

Installation Notes

Install using standard wood screws or lag screws appropriate to the mounting surface thickness and load requirements. Power down or secure any gate or door panel before removing existing hardware. Use the offset screw hole pattern as designed to maximize pull-out resistance and avoid splitting the substrate. Verify the mounting surface material and fastener size are compatible with the hinge load rating before installation.
