The base fills with water or sand rather than relying on its own mass, taking 200 lbs of water or 300 lbs of sand to hold the pole steady when a shot rattles off the rim. Above it sits a 42 by 25 inch PC backboard paired with a reinforced PE frame and a metal support bracket, a combination built for repeated impact at the edge of a pool. The rim measures 18 inches across with a polyester net and stands 3.2 feet above the base, a height that suits water play and shorter arms. Two 9-inch balls and an inflation pump come in the box, so a game starts the day it arrives. Light blue paint on bolted metal poles brings the total to 38 lbs across a 43 by 25 inch footprint. Assembly is required.
