How does it work?

The basis of our invisible inspection doors is a specially improved double hinge, protected by a European patent. This system allows the door to slide out in front of the wall and then open smoothly, which ensures easy access to inspection spaces without disrupting the design of your interior.

For this reason, it is necessary to allow for a structural opening depth of 100 mm on the hinge side. Without this preparation, the door cannot be installed.
