ULTIMATE INTERCHANGEABLE THUMB SYSTEM

CHANGING the game ONE THUMB at a time!

Product Description

“THE” Ultimate Thumb – this unique two-piece system is simple, durable and reliable! For Pro Shops, our patented auto-depth flange eliminates any guess work or need for a stopper on your drill bit. The inner contains a stopper at the bottom which will leave the thumb insert about an 1/8"-1/4" above the auto-depth feature, allowing you to use a plug-cutter for simple removal.

Our four-tab inner allows for easy, quick removal and insertion from ball-to-ball which will minimize time when needing to use multiple balls on your pair. And because the tabs are located above and below mid-point, our system doesn’t attach at the bottom therefore, any tension is evenly disbursed which nearly eliminates any possibility of breakage – allowing bowlers to focus on…Relax, Release, Repeat!

Because the outer is installed with a 9am-3pm tab placement, your hand will be in the ideal position in relation to your finger holes, after just a short quarter-turn of your thumb insert.

Secure locking of “THE” Ultimate Thumb will be felt and heard, providing the confidence that your thumb won’t move up and down, when gravity takes over during your arm swing. Our interchangeable system will be available in Pro Shops around the world!

FIND YOUR FIT to ensure the consistent fit and feel you deserve! “THE” Ultimate Thumb…Will Be Your Game Changer!

*Requires a 1-1/2" drill bit.
