Quadro runners for dishwashers have been designed for extreme conditions. A durable, reliable pull-out system that ensures perfect, smooth-running dishwasher action every day. Any food left on plates doesn't stand a chance of getting stuck because the profiles have an open structure, so leftovers are simply rinsed off and washed away. The dishwasher racks glide in and out in a silky smooth, perfectly controlled action, which keeps your tableware safe. The optional Silent System guarantees gentle and quiet rack movement, eliminating the sound of dishes clinking.
