Designed to be used with the P82 Lightweight Tuba Dent balls, this system consists of: *2- 7 foot long nylon covered cables *2- cable gripping aluminum handles *5- threaded steel driver balls *4- different length stroke cables The handles are designed to slide up and down the cable. When squeezed, they grip. They are strongly constructed of aluminum and delrin, they won't come off the cable, unless you disassemble them. The threaded drivers are made in 5 sizes. Use the heaviest driver ball you can get into the tube, which will be the one that drives the work ball back out. It takes 2 driver balls, 1 to drive it in and 1 to drive it out. The stroke cables are the cables that go between the driver balls and hold the work ball. The length of the stroke cable is determined by the length of the ball and the dent itself. The swivel makes the system easy to use. The swivel helps keep the cables from getting twisted and tangled when screwing together
