National Marker N129031 Heavy-duty Tee Hinge 4 in Zinc-plated 2-pack

Product Description

The NATIONAL MARKER N129031 is an extra-heavy-duty tee hinge built for demanding applications where mounting surfaces are narrow or where exposure to outdoor elements is a concern. Constructed from zinc-plated steel, this 4-inch hinge features a WeatherGuard coating that provides corrosion resistance in exterior environments. Offset screw holes reduce stress on the mounting surface and help prevent wood splitting under load. A tight-pin design allows installation for both right-hand and left-hand swing applications. This pack includes two hinges, making it a practical choice for paired-door installations or stocking a service vehicle.

This hinge is suited for residential and light commercial applications including barn doors, shed doors, storage bin lids, tool box lids, and gate assemblies. The narrow-profile tee design is particularly effective where standard butt hinges cannot provide adequate surface area for a secure mount. Installation is straightforward for carpenters, general contractors, or experienced DIYers working on outbuildings, agricultural structures, or utility enclosures.

Key Features

• Zinc-plated steel construction with WeatherGuard coating for outdoor corrosion resistance
• Extra-heavy-duty tee design rated for narrow mounting surfaces
• Offset screw holes reduce wood splitting risk and improve pull-out strength
• Tight-pin hinge supports both right-hand and left-hand swing applications
• Sold as a 2-pack for paired-door or dual-point hinge installations

Compatibility

Designed as a general-purpose tee hinge suitable for barn doors, shed doors, storage bins, tool boxes, and gate assemblies where a 4-inch heavy-duty hinge with a narrow mounting profile is required.

Installation Notes

Installation is typically performed with a drill, screwdriver, and appropriate wood or sheet-metal fasteners not included with the hinge. Pre-drilling pilot holes is recommended when mounting into hardwood or composite materials to take full advantage of the offset screw hole pattern. For outdoor gate or barn door applications, verify that the mounting lumber is treated or otherwise rated for exterior exposure. No special tools or licensed trade credentials are required for standard residential installations.
