Sideboard, book-case, or filing cabinet - this is a versatile system. Its assembly is self-explanatory. No tools, no screws required. Functional and flexible, the modules can be rearranged or expanded at any time. Zoll D is lightweight and yet extremely stable. The rounded front of the shelf boards takes the form of grooves into which boxes can be placed to face in four different directions. These boxes also support the next shelf. Magazine holders and displays are also available.
