This portable, adjustable system is ideal for use in gyms, multipurpose rooms, even outdoors. Rolls easily on 4"-diameter casters, and features a larger weight box that holds 325 lbs. of ballast and rubber feet for added stability. The customer must add their own ballast in the form of sand bags or similar weights. Pole system telescopes from 6-1/2' to 10'; stores easily when collapsed to minimum height. Thick-padded base and post for player safety. Direct-mount, official-sized flex goal practically eliminates stress on the aluminum-framed, 32" x 48" acrylic backboard. Some assembly required. Ships by truck.
