This sturdy, freestanding Junior Varsity Water Basketball System is made of UV-treated polyethylene to ensure outdoor durability – it will withstand rain, snow, chlorine, and sunlight for years. Its base can be easily filled with water or sand to keep it anchored to the decking or ground and its unique anti-tumbling design creates a stable platform that keeps the Junior Varsity basketball hoop safely in place. The hoop is powder coated for rust resistance and attached with stainless steel hardware. It’s easy to assemble in less than 30 minutes and includes 2 waterproof vinyl basketballs in every kit. And the specially-designed, triple-winged backboard keeps the ball in the pool for less game interruptions.
