The module includes an upper surface having two front spring loaded latches on one side and two rear tabs formed on the opposite side. A sliding or rotating surface tab is disposed between each pair of a spring loaded latch and rear tab. The module includes front and rear lower projecting steps and can be stacked on each other by inserting the steps under the rear tabs and latches. Various sized containers may be disposed on the upper surface of a module in different configurations by making use of the latches, rear tabs and sliding tabs.
