The NATIONAL MARKER N129007 is a heavy-duty tee hinge designed for use on narrow mounting surfaces where standard hinges lack the reach or strength to perform reliably. Built in a classic T-profile, this hinge delivers solid pivot support on barn doors, shed doors, storage bins, tool boxes, and gates. The black finish is applied over a galvanized steel base with a WeatherGuard coating that resists corrosion and degradation from outdoor exposure. Offset screw holes are engineered to distribute load and reduce the risk of wood splitting under stress. The tight pin design supports both right-hand and left-hand installation without modification. Sold as a 2-pack.
This hinge is suited for light construction and agricultural applications where a surface-mounted strap hinge is the standard approach. Typical installs include exterior shed and barn door hanging, garden gate hardware, utility cabinet lids, and tool box closures. The 4-inch strap length makes it appropriate for doors and panels with narrow stiles or rails where a longer hinge would overhang or interfere. Installers working on outbuildings, storage structures, and DIY utility projects will find this hinge fits standard use cases without requiring modification.
Designed as an OEM-style surface-mount tee hinge for residential and light commercial applications including barn doors, shed doors, storage bins, tool boxes, and gates with narrow mounting stiles.
Installation is performed with standard hand tools and does not require specialized trade licensing. Fasten to clean, solid wood or compatible panel material using appropriately sized wood screws through the offset screw holes. For outdoor applications, use corrosion-resistant fasteners to match the WeatherGuard coating and prevent galvanic interaction. Ensure the door or gate panel is properly supported and aligned before driving fasteners to final torque.
