The base plate 2:1 in half depth fits exactly to our 2:3 and 1:2 cubes in half depth and double width and has adjustable feet that allow the shelf to be set up without problems even on uneven ground. Even large shelving walls can thus be erected with a perfect fit without wobbling. To do this, they are simply plugged together with the help of the supplied base plate connecting clip. The material of the base plates is white coated MDF with natural edge.
