Keep basketballs safely out of the way during games and practice on a Champion Sports Basketball Cart. Each heavy-duty steel cart has four swivel casters that make it easy to move in and out of storage. A wide base keeps your cart from tipping. The larger two-shelf cart holds 18 basketballs – 12 on the bottom shelf, six on the top shelf; the smaller two-shelf cart holds 12 balls – eight on the bottom shelf, four on the top shelf.
