HEAD Tip Net Belt Once you set up an ITF mid orange or red small court on a full size court, you will know why they made the T.I.P. NET BELT. It helps you to adjust the court’s net for the ITF’s small courts without having to mess up the original setup of the net. Win-win. One more great addition to HEAD’s Tennis Instruction Program (T.I.P.), a unique approach to help players learn the game, developed in cooperation with the International Tennis Federation “Tennis Play and Stay!” campaign.
