Thanks to the reduced size and minimal design, K12 System provides a new concept of elegance in all details. The drop-down version is available in three different lengths and with a universal "zero" N strength, to suit any door dimension and weight. K12 System is an easy-to-install solution that makes additional screws unnecessary, improving the aesthetic and reducing assembling time. It operates through click-in door and side supports, sensibly reducing the risk of unsafe or improper installation. K12 System ensures a smooth and continuous movement of the door up to its maximum opening. All parts (stay excluded) are in zinc alloy nickel plated, steel and engineering plastic.
