Constructed from zinc-plated steel with a WeatherGuard galvanized coating, this hinge is rated for outdoor exposure and resists rust and corrosion from the elements. The offset screw hole pattern distributes load across the mounting surface to reduce wood splitting under stress. A tight pin design supports both right-hand and left-hand door swings without additional hardware. The hinge spans 8 inches and weighs 1.111 pounds, making it a solid choice for heavy panel and door applications.\u003c\/p\u003e\u003cp\u003eThis hinge is suited for residential and light commercial installations including barn doors, shed doors, storage bins, tool boxes, and gates. It is commonly installed by general contractors, maintenance technicians, and experienced DIYers working on outbuildings, agricultural structures, or utility enclosures. The narrow-mount design is particularly useful where traditional wide-leaf hinges cannot seat properly due to limited frame or stile width.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExtra-heavy tee hinge profile designed for narrow mounting surfaces\u003c\/li\u003e\n\u003cli\u003eZinc-plated steel construction with WeatherGuard galvanized coating for outdoor corrosion resistance\u003c\/li\u003e\n\u003cli\u003eOffset screw holes reduce wood splitting under load\u003c\/li\u003e\n\u003cli\u003eTight pin supports right-hand or left-hand swing installation\u003c\/li\u003e\n\u003cli\u003e8-inch length suitable for barn doors, shed doors, gates, tool boxes, and storage bins\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation tee hinge for barn doors, shed doors, gates, storage bins, and tool box lids requiring a narrow-mount heavy-duty hinge.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by general contractors or maintenance trades using standard hand tools. Before installation, ensure the door panel and frame are properly aligned and supported to prevent binding after the hinge is fastened. Use fasteners appropriate for the substrate material and load rating. Follow applicable local building codes when installing hardware on structural or load-bearing assemblies.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHinge Length\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Zinc-plated steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: WeatherGuard galvanized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.111 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NATIONAL MARKER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N129221\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL MARKER","offers":[{"title":"Default Title","offer_id":51344193716530,"sku":"N129221","price":57.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310550134.jpg?v=1782031353","url":"https:\/\/voomisupply.com\/products\/national-marker-n129221-8-in-heavy-duty-tee-hinge","provider":"Voomi Supply","version":"1.0","type":"link"}
