Soss 208US26D Invisible Hinge Medium Duty Satin Chrome 1 Inch Door

Product Description

The SOSS UIP ALLEGION 208US26D is a medium-duty invisible hinge designed to mount completely concealed within the door and frame, leaving no exposed hardware when the door is closed. Measuring approximately 4.3 inches in length, 2.7 inches in width, and 0.9 inches in height, this hinge is engineered for 1-inch door applications with a mortise width of 5/8 inches and a leaf length of 2-3/4 inches. The satin chrome finish provides a clean, matte appearance suited to commercial and residential interior door installations. Licensed contractors and finish carpenters install this hardware where a clean sight line and concealed hinge profile are required.

This invisible hinge is appropriate for interior doors in both residential and light commercial settings where standard butt hinges are not acceptable due to aesthetic or design requirements. The medium-duty rating positions it for use on standard-weight interior passage doors up to 1 inch thick. It is sold individually as a single unit and is typically installed in sets of two or more depending on door height and weight requirements per applicable building standards.

Installation Notes

Installation is typically performed by a finish carpenter or licensed door hardware installer. A precise mortise must be routed into both the door edge and the door frame to accept the hinge body — accurate layout and sharp chiseling are critical for proper alignment and full concealment. Power down any associated electric latch or access control hardware before beginning door work. Follow applicable local building codes for door hardware installation and fire-rated door assembly requirements where relevant.
