Soss 216US15 Invisible Hinge Medium Duty Satin Nickel

Product Description

The SOSS / UIP ALLEGION 216US15 is a medium-duty invisible hinge designed for interior doors requiring a clean, concealed pivot point. When installed, the hinge is completely hidden from view on both the door face and the jamb face, leaving no exposed barrel or leaf hardware. It is sized for 1.375-inch doors and carries a satin nickel finish for corrosion resistance and aesthetic consistency with standard interior hardware. This hinge is installed by carpenters, millwork contractors, and finish hardware installers working on residential and light commercial door applications where a traditional butt hinge would interrupt a flush surface.

The 216US15 is suited for interior door applications where surface hardware must be concealed, including passage doors, closet doors, and architectural feature doors in residential and light commercial construction. The satin nickel finish coordinates with standard interior door hardware trim. It is sold as a single unit and is intended for doors falling within the medium-duty load range at 1.375 inches in thickness.

Installation Notes

Invisible hinges require precise mortise routing into both the door edge and the door jamb; a router and hinge-specific template are the standard tools for accurate pocket cutting. Power to any electric hardware on the door assembly should be disconnected before beginning work. Follow applicable building codes and the door manufacturer's hardware specifications for hinge quantity and placement. Improper mortise depth or alignment will affect door swing and hinge longevity.
