• 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.
  
• Superior Construction - SOSS Invisible Hinges are designed to give dependable operation for years. Standard SOSS hinges are made of high strength plated steel and heavy duty zinc alloy castings.
