Soss 100CUS4 Invisible Hinge Light Duty Satin Brass

Product Description

The SOSS / UIP ALLEGION 100CUS4 is a light-duty invisible hinge designed for thin cabinet and passage doors. When installed, the hinge is completely concealed within the door edge and frame, leaving no exposed hardware on the face of the door. This makes it a preferred choice for cabinetmakers, millwork installers, and finish carpenters who need a clean, hardware-free look on interior doors and panels. The hinge measures 3/8 inches in leaf width and 1 inch in overall width, and is suited for doors ranging from 1/2 inch to 5/8 inch in thickness. The satin brass finish provides a durable, corrosion-resistant surface appropriate for interior applications.

The 100CUS4 is intended for light-duty interior applications where door thickness falls between 1/2 inch and 5/8 inch. Typical installations include cabinet doors, display case panels, interior passage doors, and furniture pieces where surface-mounted hinges are not acceptable. This hinge is sold as a pair and is suited for residential and light commercial millwork projects. Finish carpenters and cabinetmakers are the primary installers for this type of hardware.

Installation Notes

Installation is typically performed by finish carpenters or cabinetmakers using a drill press or router to mortise the hinge barrel recess into both the door edge and the frame. Power down any associated locking or electronic hardware before beginning work. Follow the manufacturer's template dimensions carefully, as the mortise depth and placement are critical to correct hinge function. Do not force the hinge into an undersized mortise, as this can damage the pivot mechanism.
