Emphasising its construction principles, the Spannkraft shelving system conveys an independent aesthetic tenor. All its functional components, such as the lashing strap, corner angles and connecting pins, are visible. The shelf can be transported as a kit, thus saving space, and be assembled at its destination without any tools in just a few minutes. Spannkraft is available in four heights and expandable in width. The optional drawers are also designed as a kit. They are folded by hand from a sheet metal blank, fixed with a strap and can be placed in the shelves where desired.
