An apparatus for adjusting the height of a basektball goal comprising a telescoping support pivotally mounted to form a diagonal within a deformable parallelogrammatic structure. The telescoping support has an outer cylinder slidably connected over a concentric inner cylinder. The inner cylinder has a slot with a plurality of notches on its underside and the outer cylinder has a post disposed inside the outer cylinder and in sliding engagement with the slot. The inner cylinder is pivotally mounted such that it may be rotated about its longitudinal axis enough to align the post with either a notch or the slot. The notches are configured such that when a notch engages the post, the telescoping support is held and restricted from extending. A release mechanism is provided to rotate the inner cylinder causing the notch to disengage the post and to align with the slot for sliding engagement with the post. So aligned, the telescoping support may be altered in length thereby changing the shape of the deformable parallelogrammatic structure and raising or lowering the basketball goal. The method of the present invention allows a user equipped with a pole and standing on the basketball playing surface to rotate the inner cylinder using the pole. The user may then raise or lower the basketball goal to the desired height using the pole. Upon removal of the pole, the telescoping support locks into position.
