The home court is where legends begin. This portable hoop system gives you a place to practice your dunk and sharpen up your jump shot. It has an acrylic backboard with a rebound rivaled only by glass. The 54″ board gives you enough room to hit angled floaters, and you can adjust the height of the heavy-duty rim with the turn of a handle. This system rests on an Ultimate Hybrid® base, which is the easiest to assemble in Spalding’s line-up. You simply load in the water and bags of sand, then cover it all up for a clean look.Spalding Ultimate Hybrid® 54″ Acrylic Portable Basketball Hoop: Backboard size: 54″ Performance acrylic board with arena-style padding 16″ offset Steel board frame with aluminum trim Arena Slam® breakaway rim 7.5′ to 10′ height adjustment Screw Jack lift Detachable handle 3.5″ oval steel pole with 20° angle Ultimate Hybrid® base fills with 19 gallons of water and four 50-pound bags of sand Rebounder on base Base dimensions: 49.8” x 29.2” x 10.2” Two wheels Includes ground stake Designed for outdoor residential play Packaging dimensions: 68.90” x 39.76” x 24.41”
