When the door is closed, the hinge conceals entirely within the door and frame, leaving a clean, uninterrupted edge with no exposed hardware. The satin nickel finish provides a durable, corrosion-resistant surface suited to high-traffic openings. Measuring 1-1\/8 inches wide by 4-5\/8 inches in length, this hinge is sized for solid wood or solid-core doors where standard butt hinges would compromise the visual finish. Installation requires precision routing and is typically performed by a finish carpenter or millwork installer.\u003c\/p\u003e\u003cp\u003eThe 218US15 is suited for interior door applications where a flush, hardware-free appearance is required. Common use cases include high-end residential entry and interior doors, hospitality millwork, and architectural cabinetry requiring a seamless closed-face profile. The heavy-duty construction handles the demands of 1-3\/4 inch door slabs without deflection or binding over repeated cycles. This hinge ships as a single unit (sold individually).\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFully concealed design — no visible hardware when door is closed\u003c\/li\u003e\n\u003cli\u003eHeavy-duty construction rated for 1-3\/4 inch door thickness\u003c\/li\u003e\n\u003cli\u003eSatin nickel finish for corrosion resistance and neutral aesthetic\u003c\/li\u003e\n\u003cli\u003e1-1\/8 inch x 4-5\/8 inch form factor for precise mortise routing\u003c\/li\u003e\n\u003cli\u003eSold individually — order quantity as needed per opening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation invisible hinge for 1-3\/4 inch solid wood or solid-core doors requiring a fully concealed hinge mortise.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a router and appropriate mortise template to achieve the precise pocket dimensions required for a flush fit in both the door edge and the door frame.
