This portable hoop system sets the stage for pick-up ball, three-point contests, and games of twenty-one until the sun goes down. It has a 54" backboard made of the same material used on the professional court. The steel breakaway rim is built to withstand double-clutch dunks and alley-oop slams, and you can adjust the height by simply turning a handle. The 40-gallon base is one of Spalding's easiest to move, with no tilting required.
