With a telescopic height adjustable pole, this unit will serve up sterner tests the higher that you set it. The height of the backboard can go from 2.3 m. right the way up to 3.05 m. This pole then supports the backboard itself, which is blow moulded & sized 110 cm. x 71 cm. x 3 cm. The base of the unit is also blow moulded & can be filled with sand or water for extra stability.
