Soss 218US26D Heavy Duty Invisible Hinge Satin Chrome

Product Description

The SOSS UIP ALLEGION 218US26D is a heavy duty invisible hinge designed for 1.75-inch doors in residential and light commercial applications. When the door is closed, the hinge body is fully concealed within the door and jamb mortises, leaving no visible hardware on the face. The 218US26D measures 1.125 inches wide by 4.625 inches long and ships with a satin chrome finish. Installation requires precise mortise routing and is typically performed by a finish carpenter or door hardware installer. The unit ships as a single hinge (EA), weighing 2 pounds.

This hinge is suited for interior wood doors in residential construction, commercial office entries, and architectural millwork where a clean, hardware-free door face is specified. The satin chrome finish coordinates with contemporary and transitional hardware schedules. The heavy duty designation makes it appropriate for solid-core doors up to 1.75 inches thick. It is commonly specified by architects and installed by millwork contractors or skilled finish carpenters during the door hanging phase of a project.

Installation Notes

Installation of invisible hinges requires a router and appropriate mortise template to achieve clean, precise pocket cuts in both the door edge and the door jamb. Power down any electronic door hardware and ensure the door is removed from the opening before beginning mortise work. Follow door manufacturer specifications for mortise depth to avoid splitting or telegraphing through the door face. This work is typically performed by a licensed finish carpenter or door hardware installer familiar with concealed hinge systems.
