Measuring 3.5 inches by 3.5 inches, this hinge features a tight pin design that accommodates both right-hand and left-hand swing configurations without additional hardware. It supports full surface and half surface mounting arrangements, giving installers flexibility depending on the gate frame and door jamb construction. Sold individually, the hinge ships boxed loose without screws, so installers should have appropriate fasteners on hand before starting the job.\u003c\/p\u003e\n\u003cp\u003eThis hinge is intended for light industrial, agricultural, and utility applications where a compact but sturdy pivot point is needed. Typical install locations include gates, barn doors, shed doors, storage bins, and tool boxes. The narrow footprint makes it well suited for frames or panels where standard wide-leaf hinges would not seat properly. Contractors, maintenance technicians, and experienced DIYers working on outbuildings, enclosures, and storage structures will find this a practical replacement or new-installation option.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot-rolled steel construction with zinc finish for corrosion resistance in outdoor and utility environments\u003c\/li\u003e\n  \u003cli\u003e3.5 inch by 3.5 inch leaf size fits narrow mounting surfaces where clearance is limited\u003c\/li\u003e\n  \u003cli\u003eTight pin design allows right-hand or left-hand swing without modification\u003c\/li\u003e\n  \u003cli\u003eCompatible with full surface and half surface mounting configurations\u003c\/li\u003e\n  \u003cli\u003eSold individually — no screws included, allowing installer to select appropriate fasteners for the substrate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation hinge for gates, barn doors, shed doors, storage bins, and tool boxes requiring a 3.5 inch heavy-duty hinge on narrow mounting surfaces.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by carpenters, maintenance technicians, or general contractors familiar with door and gate hardware. Power down any electrically operated gate systems and secure the gate leaf before removing or installing hinges. Fasteners are not included — select screws or bolts rated for the door or gate material and load. Ensure mounting surfaces are clean, plumb, and free of debris before securing the hinge leaves to prevent binding or misalignment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeaf Size\u003c\/strong\u003e: 3.5 inches x 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot-rolled steel with zinc finish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Tight pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Style\u003c\/strong\u003e: Full surface or half surface\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand\u003c\/strong\u003e: Right or left hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.677 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFasteners Included\u003c\/strong\u003e: None\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\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 MARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N223875\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL MARKER","offers":[{"title":"Default Title","offer_id":51345306353970,"sku":"N223875","price":72.12,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310550421.jpg?v=1782054216","url":"https:\/\/voomisupply.com\/products\/national-marker-n223875-heavy-duty-gate-hinge-3-5-in-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
