When installed, the hinge is completely concealed within the door and frame, leaving no visible hardware on the face of the door when it is closed. This makes it a preferred choice for high-end residential and commercial interior door installations where clean aesthetics are required. Measuring 1.375 inches wide by 5.5 inches in length, the 220US4 features a satin brass finish and is built to handle demanding applications. Licensed carpenters, millwork installers, and finish contractors are the primary trades that install this hardware.\u003c\/p\u003e\n\u003cp\u003eThe 220US4 is suited for interior door applications where surface-mounted hinges are undesirable. Common install scenarios include custom cabinetry doors, solid-core interior passage doors, and flush panel doors in residential or light commercial construction. The hinge is sold individually and is intended for use on 2-inch thick doors. Its satin brass finish coordinates with matching hardware sets in traditional and transitional interior design schemes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInvisible when door is closed — no exposed knuckle or barrel\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty construction rated for 2-inch thick doors\u003c\/li\u003e\n  \u003cli\u003eSatin brass finish for coordination with complementary door hardware\u003c\/li\u003e\n  \u003cli\u003eCompact footprint: 1.375 inches wide by 5.5 inches long\u003c\/li\u003e\n  \u003cli\u003eSold individually, one hinge per unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style invisible hinge replacement or new installation component for 2-inch thick interior doors requiring concealed hinge hardware.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a finish carpenter or millwork professional using a router and manufacturer-specified mortise template. Precise mortise depth and alignment are critical — even minor misalignment will prevent the door from closing flush or operating smoothly. Follow all applicable building codes for door hardware installation in the jurisdiction of the project. Do not force the hinge mechanism during installation, as the internal pivot components can be damaged if the mortise is undersized.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 1.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 5.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDoor Thickness\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSales Unit\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: SOSS \/ UIP ALLEGION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 220US4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOSS","offers":[{"title":"Default Title","offer_id":51563137597746,"sku":"220US4","price":109.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d5fbf69008d469e11ae7161dabb675c4.jpg?v=1786491245","url":"https:\/\/voomisupply.com\/products\/soss-220us4-heavy-duty-invisible-hinge-satin-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
