ABSTRACT:
A box has front and back walls and a bottom wall extended between the lower margins of those walls. It also has side walls that are attached to the front and back walls and close the sides of the box. Each side wall contains two panels which are joined together at a manufacturer's joint midway between the front and back walls to create a column within the side wall. The column extends all the way to the bottom wall and enhances the strength of the side wall. In one embodiment the columns in the side walls support a beam that extends through the box and items may be suspended from the beam. In another embodiment, the bottom wall folds, as do the side walls at their columns, so that the box may be supplied in a knocked-down condition.
