This is so it can fit in my rack that he is already in. It fits 3 shoebox sized tubs in each shelf. If I can find a larger one that would stretch across more area I can remove/replace two or three of the tubs with one larger tub. The problem is that it MUST be 4.5 inches tall. This is the rack
get what I am trying to do. That way it won't take up any more space in an already crowded room.
