It is built for demanding outdoor and utility applications where a narrow mounting surface limits standard hinge options. The tight pin design allows installation in either right-hand or left-hand configurations, and the offset screw holes distribute load away from the fastener centers to reduce the risk of wood splitting. Licensed contractors and experienced DIYers handling fence, barn, and storage structure work will find this hinge suited for structural-grade gate hanging.\u003c\/p\u003e\u003cp\u003eThis hinge is designed for use on gates, barn and shed doors, storage bins, and tool boxes. It supports both 2 inches x 4 inches and 4 inches x 4 inches post applications. Full surface and half surface mounting configurations are both accommodated, giving installers flexibility when working with varied framing conditions. The package contains 5 hinges, making it practical for multi-gate or multi-door installations in a single purchase.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3.5-inch heavy duty hinge sized for narrow mounting surfaces\u003c\/li\u003e\n\u003cli\u003eHot rolled steel construction for structural durability\u003c\/li\u003e\n\u003cli\u003eBlack finish suitable for exterior gate and door hardware\u003c\/li\u003e\n\u003cli\u003eTight pin allows right-hand or left-hand installation without additional hardware\u003c\/li\u003e\n\u003cli\u003eOffset screw holes reduce wood splitting risk and increase pull-out resistance\u003c\/li\u003e\n\u003cli\u003eCompatible with full surface and half surface mounting applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on gates, barn and shed doors, storage bins, and tool boxes mounted to 2 inches x 4 inches or 4 inches x 4 inches post framing in full or half surface configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by carpenters, fence contractors, or general tradespeople using standard wood screws and a drill or screwdriver.
