National Mfg N220-129 Heavy Duty Gate Hinge 3.5in Black

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N220-129 is a 3.5-inch heavy duty gate hinge manufactured from hot rolled steel with a black finish. It is built for demanding outdoor and utility applications where a narrow mounting surface limits standard hinge options. The tight pin design allows installation in either right-hand or left-hand configurations, and the offset screw holes distribute load away from the fastener centers to reduce the risk of wood splitting. Licensed contractors and experienced DIYers handling fence, barn, and storage structure work will find this hinge suited for structural-grade gate hanging.

This hinge is designed for use on gates, barn and shed doors, storage bins, and tool boxes. It supports both 2 inches x 4 inches and 4 inches x 4 inches post applications. Full surface and half surface mounting configurations are both accommodated, giving installers flexibility when working with varied framing conditions. The package contains 5 hinges, making it practical for multi-gate or multi-door installations in a single purchase.

Installation Notes

Installation is typically performed by carpenters, fence contractors, or general tradespeople using standard wood screws and a drill or screwdriver. Confirm post dimensions match the 2 inches x 4 inches or 4 inches x 4 inches design parameters before fastening. Use all provided or specified screw holes to achieve full rated holding strength. For exterior applications, verify that fastener material is compatible with treated lumber to prevent accelerated corrosion.
