Designed to help you to throw a bowling ball with precision, accuracy, and power. When set with the thumb on top of the ball, the Pro Positioner produces the normal 11 oclock to 5 oclock position enabling the ball to swing out in a true pendulum. Supports the wrist and lets the thumb release cleanly.
