National Mfg N129-155 6 Inch Black Extra Heavy T-hinge 2 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N129-155 is a 6-inch extra heavy T-hinge designed for demanding door and gate applications where standard hinges fall short. Manufactured from hot rolled steel with a black finish, this hinge delivers the structural integrity required for heavy wood doors, barn doors, shed doors, and similar installations. Offset screw holes distribute load across a wider area of the mounting surface, reducing the risk of wood splitting under stress. Each pack includes two hinges, making it a practical choice for single-door installations requiring a matched pair.

This T-hinge is suited for residential and light commercial applications including exterior wood gates, utility shed doors, barn-style doors, and fence panels. The tight-pin design allows installation for both left-hand and right-hand door swings without requiring separate hardware, simplifying procurement and reducing callbacks. It is a standard choice for carpenters, general contractors, and skilled tradespeople handling rough or finish carpentry involving heavy wood assemblies.

Key Features

• Hot rolled steel construction for high strength and durability under load
• 6-inch leaf length suited for heavy wood doors and gates
• Offset screw holes distribute fastener load to prevent wood splitting
• Tight pin design accommodates left-hand and right-hand applications

Compatibility

Designed as a heavy-duty OEM-style T-hinge replacement or new installation component for exterior wood doors, gates, and panels requiring a 6-inch surface-mount hinge.

Installation Notes

Installation is typically performed by carpenters, general contractors, or skilled DIYers using standard hand tools. Fasten with appropriately sized wood screws through the offset holes, ensuring fasteners seat fully without overdriving into the wood. For exterior applications, use corrosion-resistant screws to match the hinge service environment. Confirm door or gate weight and swing clearance before finalizing hinge placement.
