Soss 101CUS19 Light Duty Invisible Hinge Black Finish

Product Description

The SOSS UIP ALLEGION 101CUS19 is a light-duty invisible hinge designed for doors with a thickness of 1/2 inch to 5/8 inch. When installed, the hinge is fully concealed within the door and frame, leaving no exposed hardware on the face of the door. The mortised barrel mechanism allows the door to swing open without any visible pivot point. This hinge suits interior applications where a clean, hardware-free appearance is required. It ships as a pair and is appropriate for cabinetry, lightweight interior doors, and specialty millwork installations. Licensed finish carpenters and cabinetmakers are the typical installers.

The 101CUS19 is intended for light-duty interior door applications where door thickness falls between 1/2 inch and 5/8 inch. The hinge accepts a mortise pocket ranging from 3/8 inch to 1-11/16 inches, making it well suited for thin cabinet doors, decorative interior passage doors, and custom millwork panels. The black finish blends with dark-painted or ebonized door and frame profiles. Sold in pairs, this hinge is commonly specified in residential finish carpentry and custom cabinetry projects where exposed hinge hardware conflicts with the design intent.

Installation Notes

Installation is performed by licensed finish carpenters or skilled cabinetmakers using a router or chisel to cut precise mortise pockets in both the door and frame. Power down any electric latch or access-control hardware associated with the door before beginning work. Accurate mortise depth and alignment are critical — an improperly cut pocket will prevent full concealment and may bind the hinge barrel. Follow the door manufacturer and applicable local building code requirements for hinge placement and door clearances.
