Bison"s Competition Portable Basketball System is perfect for your high school or college court, because it uses the same spring technology preferred by professional and Division I collegiate arenas. Adjust the unbreakable glass backboard to the proper height for your players. The 180-degree breakaway goal stands up to heavy play and thick padding around the base protects your players from injuries. A factory-installed ballast and rear hold-down kit keep the hoop stable and prevent tipping. The steel frame is extremely sturdy, but lightweight enough for one person to set up, fold down and move to storage. The entire system rolls smoothly on eight-inch wheels that won"t scuff or mar your floor. Choose from a selection of popular colors for the base and backboard padding.
