When the door is closed, the hinge body is completely hidden within the door edge and frame, leaving a clean, uninterrupted surface. This model is sized for 1.75-inch thick doors, with a leaf face measuring approximately 1.125 inches wide by 4.625 inches long. The bright nickel finish provides corrosion resistance and a polished appearance suitable for both residential and light commercial applications. Finish carpenters, millwork installers, and door hardware specialists are the primary trades that work with this product.\u003c\/p\u003e\u003cp\u003eThe 218US14 is suited for interior passage doors, entry doors, and cabinetry applications where a traditional surface-mounted or mortise hinge would interrupt the visual line of the door and frame. The concealed barrel mechanism engages only when the door swings, keeping all hinge components recessed when closed. This makes the hinge a common choice in architectural millwork, high-end residential builds, and commercial interior door installations where clean sightlines are specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFully concealed design — hinge hardware is hidden when door is closed\u003c\/li\u003e\n\u003cli\u003eSized for 1.75-inch thick doors\u003c\/li\u003e\n\u003cli\u003eLeaf face dimensions: 1.125 inches x 4.625 inches\u003c\/li\u003e\n\u003cli\u003eBright nickel finish for corrosion resistance and clean aesthetics\u003c\/li\u003e\n\u003cli\u003eHeavy-duty construction rated for demanding door applications\u003c\/li\u003e\n\u003cli\u003eSold individually (each)\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 1.75-inch thick interior and exterior doors requiring a concealed mortise hinge solution.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires precise mortise routing into both the door edge and the door frame jamb — a router with a hinge template is standard practice. Verify door thickness and hinge mortise dimensions before cutting.
