54 Inch Portable Basketball Ring System w/ Tempered Glass Backboard Height Adjustable (2.3m-3.05m), with Stand Ring Net Designed to sit in a driveway, backyard, or any other open space, the 54-inch portable basketball system will turn your paved landscape into a jump-shooting haven. The system starts with a 54-inch (136x80cm) (54"x32") backboard with a heavy-duty steel frame. The board offers the same look and feel as pro-style glass backboards, helping you shoot layups and bank shots with confidence. The 5-inch square angled pole and massive 160-litre base with wheels offer unmatched stability. The Arena Slam breakaway rim, meanwhile, holds up well against the force of emphatic dunks--a must for modern hoops. The rim includes an institutional-style wrap with steel support braces, along with an ultra-smooth spring action that's designed to flex when pressure is applied, helping relieve stress from the backboard during gameplay.
