Switch Grip® Drilling & Installation Guide
Switch Grip® Interchangeable Thumb Inserts have revolutionized the way bowlers and pro shops use bowling balls. Bowlers now enjoy the same feel in every ball and can quickly adjust to fluctuations in thumb size without the hassles of using bowling tape. Bowling balls equipped with Switch Grip® can be shared among friends with similar insert sizes/span. Many retailers using Switch Grip™ also feature Try Before You Buy services allowing bowlers to sample different bowling balls before they purchase. Switch Grip® is used by bowlers of all skill levels and has quickly become the most accepted and widely used interchangeable thumb insert on the market.
Switch Grip® is designed to withstand over 180 lbs. of dead weight or grip pressure before possible failure. Equally important to the quality and durability of the product is proper installation. To ensure the best results, pro shops must be sure to review drilling and installation instructions before installing.
