Built from steel with an oil rubbed bronze finish, it features a square corner profile measuring 4 inches x 4 inches. The spring mechanism automatically returns the door to the closed position after each use, making it well suited for high-traffic commercial environments where self-closing function is required. Installation is performed by licensed finish carpenters, door hardware specialists, or commercial construction crews working to project specifications.\u003c\/p\u003e\n\u003cp\u003eThis hinge is intended for commercial interior door installations where a mortise-style, self-closing hinge is specified. The full mortise design requires routed recesses in both the door edge and the door frame for flush seating. The oil rubbed bronze finish coordinates with complementary architectural hardware on the same opening. Single-acting operation means the door swings in one direction only, returning automatically to the closed position through spring tension.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4 inches x 4 inches square corner profile for standard commercial door prep\u003c\/li\u003e\n  \u003cli\u003eSingle-acting spring mechanism provides automatic door closing\u003c\/li\u003e\n  \u003cli\u003eFull mortise design mounts flush with door edge and frame face\u003c\/li\u003e\n  \u003cli\u003eStandard-weight construction suited for typical commercial interior doors\u003c\/li\u003e\n  \u003cli\u003eOil rubbed bronze finish for architectural hardware coordination\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in commercial use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style commercial replacement or new-installation spring hinge for standard full-mortise door preparations accepting a 4 inches x 4 inches square corner hinge.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified door hardware technician or licensed carpenter familiar with commercial door hardware and applicable local building codes. Full mortise installation requires precise routing of door edge and frame to specified depth before setting the hinge leaves. Spring tension adjustment should be performed with the door properly supported and per the manufacturer's adjustment instructions. Ensure the door and frame prep dimensions match the hinge leaf size before installation to avoid field modification.\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 x 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Type\u003c\/strong\u003e: Square Corner\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAction\u003c\/strong\u003e: Single Acting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight Class\u003c\/strong\u003e: Standard Weight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Full Mortise\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Oil Rubbed Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.1 inches x 2.7 inches x 2.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.7 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSales Unit\u003c\/strong\u003e: EA\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: MCKINNEY HINGES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1502410B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MCKINNEY","offers":[{"title":"Default Title","offer_id":51558169411890,"sku":"1502410B","price":48.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd81cac1b34a36a5b68298c96c0ebc88.jpg?v=1786405151","url":"https:\/\/voomisupply.com\/products\/mckinney-hinges-1502410b-steel-spring-hinge-4x4-oil-rubbed-bronze","provider":"Voomi Supply","version":"1.0","type":"link"}
