An extremely robust high-quality drawer system for the storage of plate material, tools and other products. The unit has a stable, welded construction, capable of being dismantled, and in which products can be safely stored. The manually adjustable guide arms can be folded. If there are several systems placed next to each other, the rails for the guide arms can be coupled together, so that they can serve each system. The drawers (100% extractable) are normally of open construction but they can also be decked with steel or wood. The system can also be provided with a static upper mezzanine.
