Apparatus for adjusting the tension the tension and height of volleyball nets, comprising winch means and a long net cable which passes from the winch, through the bottom of the net, around pulleys attached to the pole at the other end, thence through the top of the net, and back to the pole at the winch end. Thus a single winch tightens both the top and bottom of the net in unison. The hardware can be attached to a vertical slide on each pole to provide infinite vertical adjustment over a wide range. A movable pulley can be used to double the winch pull, so a lighter winch can be used and cranking is made easier.
