The PROclassic 660 has a 36" x 60" tempered glass 3/8" backboard. It is attached to a large 6" steel post constructed out 11 gauge steel and is powder coated. The backboard has a 2.5' overhang and adjusts from 7.5-10 ft. This is a fabulous hoop for its price point. We have it displayed at our store if you want to see it in person!
