These hinges are perfect for applications where a flush fit, smooth operation and compact size are necessary. 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.

The motion path is non-circular and swings away from the cabinet, allowing for tight door clearance.

1. What are Soss Invisible Hinges?

One of the more unique hinges we supply is the Soss Invisible Hinge. It is designed so that the hinge is completely hidden when the door is closed and the riveted hinge pin is non-removable when the door is open. Additionally, once you have correctly mounted the hinges, you should never have to adjust them. We are so sure that there are no means to adjust them. When in the 180 degree opening angle, the door swings completely around and clear of the jam.
