Designed specifically for storing, transporting and displaying medicine balls, the Champion Sports Deluxe Five-Row Mobile Medicine Ball Rack features a four-sided, vertical design with five rows of single-ball shelves, giving you enough space for a total of 20 balls of any size, any weight. Manufactured entirely of welded steel, the rack's ultra-durable frame and wide-stance base deliver superior stability when in use, and its smooth-rolling, ball-bearing swivel casters make it a breeze to maneuver throughout your gym.
