Price(USD): Regular price $52.00 Sale


SOSS® Invisible Hinge model #218 is for use in wood or metal applications that are 1-3/4″ to 2″ thick. The model #218 is made of zinc and steel materials. Nylon links add strength and durability. SOSS® Invisible Hinges open a full 180° and are a single action hinge.  Now with a 20 Minute UL Fire rating!


    • Security - When closed, the SOSS Invisible Hinge cannot be seen or tampered with. When opened, the riveted hinge pin is non-removable.

    • Safety - The moving pivot point remains inside the hinge during travel until fully opened, eliminating an external pinch point on the back side of the door

    • Strength - The installed hinge is firmly anchored in a deep, full mortise, which assists the screws in supporting the door, assuring a stronger, more rigid installation.
