Soss 220US10BL Heavy Duty Invisible Hinge Oil Rubbed Bronze

Product Description

The SOSS UIP ALLEGION 220US10BL is a heavy-duty invisible hinge designed for 2-inch thick doors, delivering a clean, concealed look when the door is closed. Measuring 1.375 inches wide by 5.5 inches long, this hinge installs fully within the door and frame mortise so no hardware is visible from either side. The lacquered oil-rubbed bronze finish provides a dark, matte appearance that resists tarnishing. Weighing 4.4 pounds, the unit is built for demanding applications where both aesthetics and structural performance matter. It is specified and installed by finish carpenters, millwork contractors, and commercial door hardware professionals.

This hinge is suited for residential and light commercial interior door installations where a seamless appearance is required. Common applications include custom cabinetry, high-end residential entry and passage doors, and commercial spaces where exposed hinge hardware is architecturally undesirable. It is sized specifically for 2-inch door thickness and is sold individually as a single unit.

Installation Notes

Installation requires precise mortise routing into both the door edge and the door frame jamb — a router with a correctly sized template is the standard tool for this work. Power or battery-operated tools should be used with the door removed from the opening and laid flat on sawhorses. Follow local building codes and the door manufacturer's hardware specifications for mortise depth and hinge placement. Do not force the hinge into an undersized mortise, as this can split the door edge or prevent proper door swing alignment.
