I have 3 drawers and 2 cabinets on my worktable. One of the cabinets housed my Rubbermaid sorting box tower for components. To make sure that the whole thing wont come out and fall around on the floor I had attached it to the sides of the cabinet with screws. This is not very optimal since the cabinet is 60cm deep and the drawer tower only 20cm so there is 40cm of wasted space behind. I got plan to take use of this wasted space.
