Manufactured from hot rolled steel with a zinc finish, this 4-inch hinge is built to handle a safe working load of 23 pounds. Offset screw holes distribute load across the mounting surface to reduce the risk of wood splitting under stress. A tight pin design allows installation for left-hand or right-hand swing without modification, making it a versatile choice for residential and light commercial use.\u003c\/p\u003e\n\u003cp\u003eThis hinge is suited for exterior and interior installations where standard hinges lack sufficient strength. Typical applications include wood fence gates, shed doors, barn doors, and utility enclosures. Sold in a package of 5 units, the N129-031 is appropriate for projects requiring multiple hinges on a single door or gate panel. Installation is handled by carpenters, general contractors, or experienced DIYers working on structural door and gate assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExtra heavy duty construction rated for a 23-pound safe working load\u003c\/li\u003e\n  \u003cli\u003eOffset screw holes help prevent wood splitting at mounting points\u003c\/li\u003e\n  \u003cli\u003eTight pin design supports left-hand or right-hand door and gate applications\u003c\/li\u003e\n  \u003cli\u003eHot rolled steel base material with zinc finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e4-inch hinge size suits standard gate and utility door installations\u003c\/li\u003e\n  \u003cli\u003eSold as a package of 5 hinges per unit of measure\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation T-hinge for residential and light commercial wood gate, shed door, and barn door applications requiring a 4-inch extra heavy hinge.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by carpenters or general contractors using standard woodworking hand tools and appropriate wood screws. Before installing, confirm the mounting surface lumber is sound and free of rot to ensure the offset screw holes achieve full holding strength. Pre-drilling pilot holes is recommended to avoid splitting the wood even with the offset hole pattern. Always verify the door or gate is properly supported before final fastening to prevent hinge misalignment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHinge Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Rolled Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSafe Working Load\u003c\/strong\u003e: 23 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5 per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.85 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NATIONAL MFG\/SPECTRUM BRANDS HHI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N129-031\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL HARDWARE","offers":[{"title":"Default Title","offer_id":51563434606898,"sku":"N129-031","price":66.77,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e29ff1d53ebb848fc140426603b98f2d.jpg?v=1786497420","url":"https:\/\/voomisupply.com\/products\/national-mfg-n129-031-4-in-zinc-extra-heavy-t-hinge-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
