Soss 212US15 Invisible Hinge Satin Nickel Medium Duty

Product Description

The SOSS 212US15 is a medium duty invisible hinge designed for interior doors with a thickness of 1-1/8 inches. When installed, the hinge conceals completely within the door and frame, leaving no hardware visible from either side when the door is closed. The satin nickel finish provides a clean, neutral appearance suited to modern and transitional interiors. At 0.8 pounds, the hinge is compact and self-contained. Installation requires precise mortising into both the door edge and the frame jamb, making this a task typically performed by a finish carpenter or experienced door installer.

This hinge is intended for residential and light commercial interior door applications where concealed hardware is specified. It is a practical choice for passage doors, closet doors, and interior panel doors where a flush, hardware-free appearance is desired. The 212US15 is sold as a single unit and is suited to doors requiring medium duty hinge support at standard residential door thicknesses.

Installation Notes

Installation requires routing or chiseling precise mortises into both the door edge and the door frame jamb to accept the hinge body. Power down any associated door hardware or access control systems before beginning work. A router with a straight bit and a proper hinge mortise jig is strongly recommended to achieve the tight tolerances required for invisible hinges. Follow local building codes for door hardware installation in commercial applications.
