Contour Power Grips Power Taper Thumb Sleeve

This pre-formed vinyl thumb insert features a round hole design that tapers smaller towards the bottom of the thumb hole with an added round bump toward the top of the hole for a stronger grip. The soft material will give you a better grip than urethane thumb inserts and it trims easily with a sharp utility knife. 

- Vinyl oval thumb insert with 1 1/8 outside diameter.

    I have used Power Thumb Inserts before and really liked them.

    Many of my bowlers have tried these. They like the feel of a secure fit combined with a quick release.

    These sleeves require a 1-1/8 bit. However some fit slightly smaller and require a 1-3/32 for proper fit. Test fit in a scrap ball before drilling.
