The Pro line of basketball systems incorporates the highest-quality manufacturing standards with the best features in the industry. The secure in-ground anchor system and 6" powder-coated steel pole creates a stable foundation that cuts down on vibration and torque, and the 72" tempered-glass backboard delivers superior ball response and feel. Extension arms are available in both 36" and 48" lengths. In addition, the pole and backboard have edge pads, a sturdy and reliable height adjustment mechanism, and a stop bar to be sure that even younger children can safely raise and lower the basket to their heart’s content.
