When the door is closed, the hinge is completely hidden within the door edge and frame, leaving no exposed hardware on either face. This makes it a common choice for high-end residential millwork, cabinetry, and architectural door applications where aesthetics are a priority. The 216US3 carries a bright brass finish and is sized at 1 inch by 4-5\/8 inches, suited for 1-3\/8 inch thick door stock. Installation is typically performed by finish carpenters, cabinetmakers, or experienced trim contractors.\u003c\/p\u003e\n\u003cp\u003eThe 216US3 is intended for medium-duty interior door applications where a traditional butt hinge or surface-mounted hinge would interrupt the visual plane of the door. Typical installations include residential passage doors, closet doors, and interior architectural doors up to 1-3\/8 inches thick. The bright brass finish coordinates with brass or gold-tone hardware sets. This hinge is sold individually and is designed to be mortised into the door edge and corresponding jamb or frame.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFully concealed when door is closed — no exposed hinge knuckles or barrels on door face\u003c\/li\u003e\n  \u003cli\u003eMedium-duty rating suitable for standard interior passage doors\u003c\/li\u003e\n  \u003cli\u003eFits 1-3\/8 inch thick door stock\u003c\/li\u003e\n  \u003cli\u003eBright brass finish for coordination with complementary hardware finishes\u003c\/li\u003e\n  \u003cli\u003eCompact footprint: 1 inch wide by 4-5\/8 inches in length\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 replacement or new-installation invisible hinge for interior wood doors measuring 1-3\/8 inches in thickness, consistent with standard residential passage door stock.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires precise mortising into both the door edge and the door frame or jamb; a drill press or router with a proper mortising template is strongly recommended to achieve the tight tolerances this hinge requires. Verify door thickness is 1-3\/8 inches before ordering, as invisible hinges are not adjustable for thickness variation. Do not attempt to force the hinge into an undersized mortise, as this can crack the door edge or distort the hinge body. Follow the manufacturer-provided template for mortise depth and placement to ensure proper swing clearance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHinge Width\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHinge Length\u003c\/strong\u003e: 4-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDoor Thickness Compatibility\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuty Rating\u003c\/strong\u003e: Medium Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright Brass (US3)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5 inches (L) x 4 inches (W) x 1.4 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\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: 216US3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOSS","offers":[{"title":"Default Title","offer_id":51564279529778,"sku":"216US3","price":109.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/994e3bbbe71c6b0b8626e1680ca4ae6b.jpg?v=1786516198","url":"https:\/\/voomisupply.com\/products\/soss-216us3-invisible-hinge-medium-duty-bright-brass-1-3-8in","provider":"Voomi Supply","version":"1.0","type":"link"}
