This portable hoop is built around one idea: the rim should meet the player, not the other way around. Install the middle tube and the rim runs 7.7 to 10 ft pull it out and the range drops to 4.9 to 7.2 ft, ten levels in total. A safety locking latch holds the setting, so the height you choose is the height you get through a full afternoon of games.The 39 in wide, 26 in tall backboard is shatterproof and carries a reinforced metal bracket behind it, while an anti-tear net and robust metal rim take the punishment of daily shooting. Stability comes from two places: a base that fills with 110 lbs of water or 176 lbs of sand, and a free weight bag measuring 23.5 by 15.5 by 10 in that holds another 110 lbs of sand. Together they anchor the 46 lb system through drives and rebounds. Thickened metal tubes keep the frame rigid, two 3.5 in transport wheels make it portable, and a built-in ball holder keeps the game organized, indoors or out.
