National Mfg N129-031 4 in Zinc Extra Heavy T-hinge 5 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N129-031 is an extra heavy T-hinge designed for demanding gate, barn door, and utility door applications. Manufactured from hot rolled steel with a zinc finish, this 4-inch hinge is built to handle a safe working load of 23 pounds. Offset screw holes distribute load across the mounting surface to reduce the risk of wood splitting under stress. A tight pin design allows installation for left-hand or right-hand swing without modification, making it a versatile choice for residential and light commercial use.

This hinge is suited for exterior and interior installations where standard hinges lack sufficient strength. Typical applications include wood fence gates, shed doors, barn doors, and utility enclosures. Sold in a package of 5 units, the N129-031 is appropriate for projects requiring multiple hinges on a single door or gate panel. Installation is handled by carpenters, general contractors, or experienced DIYers working on structural door and gate assemblies.

Installation Notes

Installation is typically performed by carpenters or general contractors using standard woodworking hand tools and appropriate wood screws. Before installing, confirm the mounting surface lumber is sound and free of rot to ensure the offset screw holes achieve full holding strength. Pre-drilling pilot holes is recommended to avoid splitting the wood even with the offset hole pattern. Always verify the door or gate is properly supported before final fastening to prevent hinge misalignment.
