When the door is closed, the hinge is completely concealed within the door and frame, leaving no visible hardware on the face. This design provides a clean, uninterrupted appearance along the door edge. The 218US5 features an antique brass finish and is built to handle the demands of heavy door use. Licensed HVAC, plumbing, and electrical trades aside, this hinge is primarily installed by finish carpenters, millwork contractors, and general contractors working on interior door projects.\u003c\/p\u003e\n\u003cp\u003eThe 218US5 is suited for interior door installations where a concealed hinge is required or preferred for aesthetic or security reasons. It fits 1-3\/4 inch thick doors and provides a mortised, flush-mount installation. The antique brass finish makes it appropriate for traditional or transitional interior settings. It is sold individually and is commonly specified in custom millwork, cabinetry, and high-end residential door installations where exposed butt hinges are not desired.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFully concealed design — hinge is invisible when the door is closed\u003c\/li\u003e\n  \u003cli\u003eDesigned for 1-3\/4 inch thick doors\u003c\/li\u003e\n  \u003cli\u003eAntique brass finish for traditional interior applications\u003c\/li\u003e\n  \u003cli\u003eHeavy duty construction for demanding door use\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit (each)\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 1-3\/4 inch thick interior doors requiring a fully concealed mortise hinge.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of invisible hinges requires precise mortising into both the door edge and the door frame jamb.
