When installed correctly, the hinge barrel is fully concealed within the door and frame, leaving no exposed hardware on the face of the door. This makes it a preferred choice for finish carpenters, millwork installers, and door hardware specialists who want a clean, uninterrupted surface on both the door slab and the jamb. The antique brass finish provides a classic appearance on applications where visible hardware would otherwise detract from the design intent. The hinge measures 4.8 inches in length and 1.2 inches in height and ships as a single unit.\u003c\/p\u003e\n\u003cp\u003eThis invisible hinge is suited for residential and light commercial interior door installations where a flush, hardware-free appearance is required. Typical applications include cabinet doors, passage doors, and architectural millwork projects where surface-mounted hinges are not acceptable. It is appropriate for doors rated at medium-duty load levels and is intended for doors measuring 1-3\/8 inches in thickness. Installation requires precise mortising into both the door edge and the door frame jamb.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFully concealed barrel — no visible hinge hardware when door is closed or open\u003c\/li\u003e\n  \u003cli\u003eMedium-duty construction rated for 1-3\/8 inch door thickness\u003c\/li\u003e\n  \u003cli\u003eAntique brass finish for traditional or period-appropriate architectural applications\u003c\/li\u003e\n  \u003cli\u003eCompact profile: 4.8 inches length, 3.7 inches width, 1.2 inches height\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit — quantity one per order\u003c\/li\u003e\n  \u003cli\u003eLightweight at 1.7 pounds, reducing added load on door and frame\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation invisible hinge for interior doors with a 1-3\/8 inch thickness requiring a medium-duty concealed hinge solution.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of invisible hinges requires precise mortise routing into both the door edge and the door frame jamb — use a dedicated invisible hinge jig or router template for accurate placement. A licensed carpenter or experienced door hardware installer should perform the work, as misalignment will prevent proper door swing and closure. Ensure the door is fully supported and stationary before mortising. Follow applicable local building codes for door hardware installation in commercial occupancies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.7 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Antique Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuty Rating\u003c\/strong\u003e: Medium Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Door Thickness\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSales Unit\u003c\/strong\u003e: Each (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: SOSS UIP ALLEGION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 216US5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOSS","offers":[{"title":"Default Title","offer_id":51558979567922,"sku":"216US5","price":110.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0847d6b0a9daee99b99731b83ffdc4e9_4c47f645-d6f9-425b-9928-d00c135b5567.jpg?v=1786424695","url":"https:\/\/voomisupply.com\/products\/soss-216us5-invisible-hinge-antique-brass-medium-duty","provider":"Voomi Supply","version":"1.0","type":"link"}
