The Ball Caddy is a great Quick Start Tennis accessory designed to make your life on the court more fun and convenient. Just hang your Ball Caddy on the top of your 18-foot portable net vertical pole, hang it on a regular tennis net, or on a nearby fence. Stores up to 10 red-level felt balls or 12 each of your orange-level, green-level or regular tennis balls to minimize time wasted for ball pick-up during play! Remember that you are out there to play and not to spend half your time chasing down and picking up balls! Suggest setting up each 36-foot court (that uses 18-foot portable or permanent nets) with its own Ball Caddy full of balls before the kids even get on the court! Being well organized gets noticed by parents and onlookers alike.
