Soss 203CUS19 Invisible Hinge Light Duty Black

Product Description

The SOSS 203CUS19 is a light-duty invisible hinge designed for interior doors with a thickness of 3/4 inch. When closed, the hinge is completely concealed within the door and frame, leaving a clean, uninterrupted surface. Finished in black, this hinge is sold as a pair and weighs 0.3 pounds. The mortised design eliminates exposed knuckles and barrels, making it a practical choice for cabinet doors, passage doors, and interior architectural millwork where a flush appearance is required. Installation is typically performed by finish carpenters, millwork installers, or general contractors.

This hinge is suited for light-duty residential and light commercial applications on 3/4 inch doors. Typical use cases include interior cabinet doors, furniture panels, and lightweight passage doors where a concealed hinge is specified for aesthetic or functional reasons. The black finish allows it to blend with dark-toned hardware and door frames without visible hardware interrupting the surface plane.

Installation Notes

Installation requires precise mortising into both the door edge and the frame jamb — a router with a hinge template is the standard tool for this operation. Power down any associated electrical or access-control hardware before servicing the door assembly. Follow local building codes for door hardware installation in commercial applications. Do not exceed the rated load capacity for which this light-duty hinge is designed.
