Soss 216US26D Invisible Hinge Satin Chrome 1-3/8 Inch Door

Product Description

The SOSS UIP ALLEGION 216US26D is a medium-duty invisible hinge designed for interior doors with a thickness of 1-3/8 inches. When installed, the hinge is fully concealed within the door and frame, leaving no exposed hardware when the door is closed. The satin chrome finish provides a clean, matte appearance suited to modern or commercial interior applications. This hinge installs as a mortised unit, requiring precise routing into both the door edge and the door frame jamb. Installation is typically performed by carpenters, finish carpenters, or general contractors on interior door assemblies.

The 216US26D is intended for medium-duty residential and light commercial interior door applications where a clean, hardware-free door face is desired. It is well suited for use in office interiors, hospitality spaces, and upscale residential projects where visible hinge hardware would detract from the finished appearance. The satin chrome finish coordinates with standard contemporary hardware finishes. The hinge accommodates 1-3/8 inch door thickness, which is standard for most interior passage doors.

Installation Notes

Installation requires precise mortise routing into both the door edge and the frame jamb using a drill press or router template; improper routing depth will prevent full concealment or cause binding. Carpenters and finish tradespeople should follow the manufacturer template and verify door thickness before ordering. Always confirm the door is properly supported and stationary before mortising. Follow applicable local building codes for door hardware installation in commercial occupancies.
