Soss 203CUS26D Invisible Hinge Light Duty Satin Chrome

Product Description

The SOSS UIP ALLEGION 203CUS26D is a light-duty invisible hinge designed for doors with a 3/4 inch thickness. It installs fully concealed within the door and frame, leaving no visible hardware when the door is closed. The hinge measures 1/2 inch by 1-3/4 inch and ships as a pair, making it suited for interior applications where a clean, unobstructed appearance is required. Finish is satin chrome for corrosion resistance and a neutral aesthetic that blends with most hardware sets. Carpenters, finish trim contractors, and commercial door installers commonly specify this hinge where surface-mounted hardware is undesirable.

The 203CUS26D is intended for light-duty interior door installations in residential and light commercial settings. Its invisible design suits applications such as passage doors, closet doors, and interior office doors where aesthetics and hardware minimalism are priorities. Because the hinge mortises fully into the door edge and jamb, it is typically paired with precise routing work. The satin chrome finish coordinates with standard door hardware finishes across a wide range of interior door styles.

Installation Notes

Installation requires precise mortise routing into both the door edge and the door jamb; a router with a hinge-mortise template is the standard tool for this work. Power down or disconnect any electrified hardware before working on the door assembly. Follow local building codes for door hardware requirements, particularly in commercial applications subject to accessibility standards. Do not force the hinge barrel during alignment, as the concealed mechanism requires accurate mortise depth to operate correctly.
