An height adjustable backboard assembly having a pair of vertically oriented concentric glide tubes, the inner of which may slide within the outer. The top and bottom of the inner glide tubes are connected to mounting brackets to which a basketball backboard may be fastened. The outer glide tubes are connected to a pair of cross bracket members which are in turn fastened to an existing support frame extending from the wall or ceiling adjacent a basketball court. The inner glide tubes may be moved relative to the outer glide tubes by a threaded screw shaft which is carried in a shaft housing permitting free rotation of the screw shaft, and rotated by a hand crank or motor.
