Soss 204CUS15 Invisible Hinge Satin Nickel 3/4 Inch Doors

Product Description

The SOSS UIP ALLEGION 204CUS15 is a light-duty invisible hinge designed for 3/4-inch interior doors where a clean, hardware-free appearance is required. The hinge installs fully concealed within a routed mortise in the door and frame, leaving no exposed barrel or leaf when the door is closed. With a satin nickel finish, it blends with contemporary door hardware and is sold as a pair. The compact folded profile measures approximately 0.6 inches in height, making it suited for lightweight doors in residential and light commercial millwork applications.

This hinge is intended for use on 3/4-inch doors such as cabinet doors, interior passage doors, and lightweight panel doors. The mortise-mount design makes it a common choice for finish carpenters, cabinetmakers, and millwork installers who need a flush, gap-free appearance on door faces. It is not intended for heavy exterior doors or high-traffic fire-rated door assemblies. Installation requires precision routing to achieve proper alignment and smooth swing operation.

Key Features

• Fully concealed installation — no visible hardware when door is closed
• Designed for 3/4-inch door thickness
• Satin nickel finish for compatibility with contemporary hardware sets
• Light-duty rating appropriate for cabinet and lightweight interior doors
• Sold as a pair (PR) per unit of sale
• Compact folded height of 0.6 inches minimizes mortise depth requirements

Compatibility

Designed as an OEM-style replacement or new-installation invisible hinge for 3/4-inch lightweight interior doors and cabinet doors requiring a fully concealed hinge solution.

Installation Notes

Installation is performed by finish carpenters or cabinetmakers using a router and template to cut precise mortises in both the door edge and door frame or cabinet face. Verify mortise dimensions against the hinge body size before routing to ensure a flush fit. Test swing and alignment before final fastening, as concealed hinges allow limited adjustment once set. Follow local building codes for any door hardware used in rated assemblies.
