Available from Vauth-Sagel, Cornerstone is a swiveling system component for corner cabinets that automatically extends the entire contents out of the cabinet upon opening the door. Because the travel path is controlled and is confined to the area of the corner cabinet case, it doesn't impede neighboring cabinets or the dishwasher. The 85-degree opening angle also has been optimized so the corner cabinet does not impact with other front panels, handles or walls. The corner cabinet can be equipped with large shelves of up to 28.5 cubic centimeters in surface area.
