25" red tube
The cord, latex tube and ball on their own. No pole or base, and it doesn't mount to one. A partner swings it overhead for the batter. Ships anywhere.
Looking for one that mounts to a pole? The Pro Sleeve System sets into the ground, and its sleeve fits any 3-inch pole. See the Pro Sleeve
