Soss 106UNP Invisible Hinge Light Duty Unplated

Product Description

The SOSS 106UNP is a light-duty invisible hinge designed for metal doors in residential and light commercial applications. When closed, the hinge sits fully concealed within mortised pockets on the door and frame, leaving no visible hardware on the face of the door. This makes it a common choice for projects where a clean, uninterrupted door edge is required. The 106UNP ships in an unplated finish and is sold as a pair. Installation requires precise mortise routing and is typically performed by finish carpenters, millwork contractors, or skilled door-hardware technicians.

This hinge is suited for metal door applications where surface-mounted hardware is undesirable. The invisible design works by folding its pivot arms inside the door edge during closing, fully hiding the mechanism. It is appropriate for interior metal doors in light-duty settings. Each unit is sold as a pair, with a case quantity of five pairs. The unplated finish allows for field painting or coating to match the surrounding door finish as required by the project.

Installation Notes

Installation of invisible hinges requires accurate mortise pockets routed into both the door edge and the door frame jamb. All door hardware installation should follow applicable building codes and the door manufacturer's specifications. Ensure the door is fully supported and de-tensioned before removing existing hardware on replacement jobs. Do not force the hinge arms during installation, as improper seating can cause binding or misalignment.
