Soss 216US26 Heavy Duty Invisible Hinge Bright Chrome

Product Description

The SOSS / UIP ALLEGION 216US26 is a heavy duty invisible hinge designed for 1-3/8 inch thick doors. When installed, the hinge is fully concealed within the door and frame, leaving no exposed hardware on the face of the door. This design is common in commercial and residential applications where a clean, unobstructed door edge is required. The hinge measures 1 inch by 4-5/8 inches and carries a bright chrome finish. Installation requires mortising into both the door edge and the door frame jamb, making it a job for finish carpenters, millwork crews, or experienced door hardware installers.

The 216US26 is suited for interior door applications where concealed hardware is specified by architects, designers, or building owners. It is appropriate for 1-3/8 inch doors in both residential and light commercial settings. The bright chrome finish coordinates with chrome door hardware and trim. This hinge is sold individually and is typically specified in pairs or sets depending on door weight and height. Applications include office doors, interior residential doors, and custom millwork installations where exposed hinges are not acceptable.

Installation Notes

Installation of invisible hinges requires precise mortising into both the door edge and the door frame using a router or specialized jig — improper mortise depth will prevent smooth operation. Power down or secure any electronic door hardware before beginning installation. Follow applicable building codes and door hardware specifications for hinge count and placement based on door size and weight. This work is typically performed by a finish carpenter, door hardware installer, or millwork professional.
