Pre-made thumb slugs to fit your non-round thumb! Those with "flatter" thumbs, this is the slug for you! Pre-made to fit your thumb without making hardly any changes! Comfortable and consistent release! The Pro V2 is the popular "Box Oval" shape made with a vinyl material preferred by Pro Shop Operators.
The box oval shape works great for a clean release. The material is easy to work but also takes a very smooth finish. Compared to plain oval inserts, very little material needs to be removed to fit the bowler. Compared to round inserts very little tape is ever needed; great product that everyone should try. The sizes are quite consistent from one lot to the next.
How would I measure for one?
Hi, we would suggest getting fitted at a local pro shop for precise measurements, but you can you measure the width of the widest part of your thumb if you have a tool that measure to the 64ths.
If I measure the wide part of the thumb, what would the narrow part be
Unfortunately, they don't give a measurement for the height. We sell a round insert if you feel that the height needs to be similar to the width, but if you know if your thumb is wider than it is tall then the oval would be the better option.
Can I put this insert into a turbo grip insert sleeve?
You would have to make sure that you get the Inner Thumb Sleeve that says "Empty" so that it would allow for you to insert this insert.
Is the measurement for the narrow part or the wide part?
