Technological advancement means pushing limits. Until recently it was completely unthinkable that a strong flap stay could be fully integrated into the side wall of a wall cabinet. Kinvaro T-Slim makes this vision a reality. In this respect the new flap stay truly crosses the frontiers of physics. It is a pioneering achievement of the GRASS developers. Engineers have succeeded in reducing the size of the complex mechanics of the flap-up fitting to a compact 12 mm. Twelve millimetres that will change furniture making.
