Soss 218ICUS15 Invisible Spring Hinge Satin Nickel 1-3/4 in Door

Product Description

The SOSS 218ICUS15 is a heavy-duty invisible spring hinge designed for 1-3/4 inch thick interior and exterior doors. When installed, the hinge body is fully concealed within the door and frame, leaving no visible hardware on the face of the door. The 218ICUS15 measures 1-1/8 inches in width by 4-5/8 inches in length and ships with a Satin Nickel finish. The integrated spring mechanism provides automatic self-closing action without a separate closer. This hinge is installed by finish carpenters, cabinetmakers, and door hardware technicians working on residential and light commercial projects where a clean, hardware-free door face is required.

The 218ICUS15 is suited for 1-3/4 inch door applications where concealed hardware is specified. Common install scenarios include interior passage doors, office doors, and specialty architectural doors where surface-mounted hinges are not acceptable by design specification. The Satin Nickel finish is compatible with standard ANSI 15 finish hardware sets, making it straightforward to coordinate with existing locksets and other door hardware on the same project.

Compatibility

Installation Notes

Installation requires precise mortise routing in both the door edge and the door frame jamb; a drill press or router with a correctly sized bit is strongly recommended for accurate pocket depth. Power down any electric strike or access control hardware associated with the door before beginning work. Spring tension adjustment should be made with the door hanging and the hinge fully seated in its mortises. Consult applicable building codes for door closer and egress requirements when specifying self-closing hardware on rated assemblies.
