Product Description
The SOSS 220US4 is a heavy-duty invisible hinge designed for doors measuring 2 inches thick. When installed, the hinge is completely concealed within the door and frame, leaving no visible hardware on the face of the door when it is closed. This makes it a preferred choice for high-end residential and commercial interior door installations where clean aesthetics are required. Measuring 1.375 inches wide by 5.5 inches in length, the 220US4 features a satin brass finish and is built to handle demanding applications. Licensed carpenters, millwork installers, and finish contractors are the primary trades that install this hardware.
The 220US4 is suited for interior door applications where surface-mounted hinges are undesirable. Common install scenarios include custom cabinetry doors, solid-core interior passage doors, and flush panel doors in residential or light commercial construction. The hinge is sold individually and is intended for use on 2-inch thick doors. Its satin brass finish coordinates with matching hardware sets in traditional and transitional interior design schemes.

Installation Notes
Installation is typically performed by a finish carpenter or millwork professional using a router and manufacturer-specified mortise template. Precise mortise depth and alignment are critical even minor misalignment will prevent the door from closing flush or operating smoothly. Follow all applicable building codes for door hardware installation in the jurisdiction of the project. Do not force the hinge mechanism during installation, as the internal pivot components can be damaged if the mortise is undersized.
