The Tourna Ballport 200 Deluxe Tennis Ball Cart is a handy way to transport and teach with up to 200 balls. The three-wheel dolly design provides a third wheel in the front, making it a snap to maneuver over curbs, around the court and up and down steps. This portable dolly cart collapses easily and is able to fit in the trunk or rear of most vehicles to provide easy transportation to and from the tennis court. The lid is made of wire and features a snap shut closure to prevent balls from spilling out. The lid can also be padlocked for extra security when needed. This ball cart is suitable for serious players, teaching pros and coaches.
