Soss 216ICUS26D Invisible Spring Hinge Satin Chrome

Product Description

The SOSS UIP ALLEGION 216ICUS26D is a heavy-duty invisible spring hinge designed for doors with a 1-3/8 inch thickness. It mounts fully concealed within the door and frame, leaving no visible hardware on the face of the door when closed. The hinge measures 1 inch wide by 4-5/8 inch in length and ships in a satin chrome finish. The integrated spring mechanism provides controlled, automatic return for light to medium-weight interior doors. Weighing 2.5 pounds, it is built for installations where a clean sightline and professional finish are required. Carpenters, millwork contractors, and commercial door installers are the primary trades for this fitting.

The 216ICUS26D is suited for interior residential and light commercial door applications where concealed hardware is specified, such as custom cabinetry, passage doors, and architectural millwork projects. It is intended for doors measuring 1-3/8 inch thick and is installed during door prep before hanging. The satin chrome finish coordinates with contemporary hardware packages. The spring-loaded design eliminates the need for a separate door closer on lighter interior doors.

Installation Notes

Installation requires precise mortising into both the door edge and the door frame jamb to achieve the fully concealed fit. A licensed carpenter or experienced door installer should perform the mortise routing using a template jig appropriate for the 216ICUS26D profile. Ensure the door is properly supported and all finish work is complete before final hinge installation. Follow local building codes for hardware requirements on rated assemblies where applicable.
