Keeping sports balls organized and off the floor, this rolling storage cart uses vertical stacking to save valuable space in gyms, garages, and schools. Constructed entirely from Q235B carbon steel with a painted finish, it stands up to heavy loads while wiping clean with a damp cloth. Four swivel wheels roll smoothly across floors and rough terrain alike, and two of them lock to hold the cart securely in place. Five elastic straps span the front opening to keep balls contained yet easy to grab from the bottom, preventing them from rolling loose during transport. Roomy enough for basketballs, soccer balls, volleyballs, and rugby balls, the cage suits homes, schools, gyms, clubs, and playgrounds. A stackable design lets you add units as your storage needs grow.
