A folding plastic box has two spaced parallel rails for supporting hanging files. Casters may be attached to the bottom of the box by plastic fasteners. The casters have base plates which fit fairly snuggly into the bottom areas of box-like cells formed on the bottom of the box. Plastic fasteners retain the casters in position. The walls of the box-like cells prevent lateral displacement of the casters. Also, the boxes may be transported on a dolly which has the casters attached to the bottom thereof.
