Built from steel with a satin brass finish, this hinge measures 4 inches x 4 inches with a 5\/8 inch radius corner profile. The full mortise design requires a routed pocket in both the door edge and the door frame, resulting in a flush, clean installation. Licensed carpenters, door hardware installers, and general contractors typically install this hinge during new construction or door replacement projects. The spring mechanism provides controlled door closing without a separate closer unit.\u003c\/p\u003e\n\u003cp\u003eThis hinge is suited for residential interior and light-duty door applications where a self-closing function is needed. Common install scenarios include utility rooms, stairwell doors, and any door required by local code to self-close. The satin brass finish coordinates with standard residential hardware sets. Per the supplier data, this item must be ordered in multiples of 2, as spring hinges are installed in pairs on most residential door configurations to ensure balanced operation and even spring tension distribution across the door.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFull mortise design for flush, recessed installation in door edge and frame\u003c\/li\u003e\n  \u003cli\u003eBuilt-in spring mechanism provides automatic door return without a separate closer\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in residential applications\u003c\/li\u003e\n  \u003cli\u003e4 inches x 4 inches leaf size with 5\/8 inch radius corners for standard residential fitment\u003c\/li\u003e\n  \u003cli\u003eSatin brass finish for compatibility with common residential hardware finishes\u003c\/li\u003e\n  \u003cli\u003eMust be ordered in multiples of 2 to complete a proper hinge set\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-construction spring hinge for standard residential full mortise door applications requiring a 4 inches x 4 inches hinge with 5\/8 inch radius corners.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this full mortise spring hinge requires precise routing of mortise pockets in both the door edge and the door jamb to achieve a flush fit. A licensed carpenter or experienced door hardware installer should verify door thickness and frame material before routing. Adjust spring tension only with the proper hinge pin tool — never remove the hinge pin while the door is under spring load. Follow applicable local building codes for self-closing door requirements, particularly in fire-rated or code-mandated egress applications.\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 Radius\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHinge Type\u003c\/strong\u003e: Full Mortise Spring Hinge\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: Satin Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 4.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 2.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 0.65 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.9 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSales Unit\u003c\/strong\u003e: Each (must be ordered in multiples of 2)\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: HAGER HINGE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 175444\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HAGER","offers":[{"title":"Default Title","offer_id":51557401362738,"sku":"175444","price":18.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29fe033b1ea5cb943f7450100ef50bae.jpg?v=1786387371","url":"https:\/\/voomisupply.com\/products\/hager-hinge-175444-full-mortise-spring-hinge-4x4-steel-satin-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
