The pull-out shelves can be easily mounted on the four 19" profile rails of your 19" cabinets. They are made of sturdy, perforated metal with a high load-bearing capacity and therefore provide an ideal storage surface for your components. A handle included in the scope of delivery can be attached to make it easier to pull out the shelves. The shelves are available in grey (RAL 7035) and black (RAL 9005).
