National Mfg N129-189 Extra Heavy T-hinge 6 Inches Zinc 5-pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N129-189 is a 6-inch extra heavy T-hinge finished in zinc, designed for high-load gate, door, and barn applications where standard hinges are undersized for the job. Manufactured from hot rolled steel, this hinge features offset screw holes that distribute fastener stress away from the wood grain, reducing the risk of splitting under load. The tight pin design allows installation for both left-hand and right-hand swing configurations without additional hardware. Each hinge carries a safe working load of 48 pounds. This listing includes a pack of 5 hinges.

This T-hinge is suited for heavy-duty residential and light commercial installations including wood gates, shed doors, barn doors, and fence panels. The zinc finish provides corrosion resistance in outdoor and semi-exposed environments. The offset screw hole pattern is particularly useful when fastening into older or softer wood stock where standard centered holes risk splitting. Installers working on agricultural fencing, utility buildings, or exterior access panels will find this hinge appropriate for demanding field conditions.

Installation Notes

Installation is typically performed by carpenters, general contractors, or experienced DIYers using standard wood screws and a drill or screwdriver. Pre-drilling pilot holes is recommended, especially in hardwood or weathered lumber, to take full advantage of the offset hole pattern. Ensure the mounting surface is structurally sound and that the combined weight of the door or gate panel does not exceed the rated safe working load per hinge. Use an appropriate number of hinges per panel weight and size per applicable building guidelines.
