The Upright adjusts to the desired height by simply adjusting the inner pipe upward. It works on an internal ball-bearing (slip-lock) system, so as you raise the inner pipe the weight locks the upright into place. To release, and lower back down, simply raise the inner pole to release the pressure, lift the ring and guide the inner pipe down.
