The Jack

Aids in lifting an Inner Sleeve insert up and out of a tight thumb hole. Removable inserts can become difficult to remove when a ball core expands due to hot/cold climate changes or simply over time as the ball absorbs lane oil. Ball core expansion puts pressure on the Switch Grip Outer Sleeve which causes difficulty in removing or turning the Inner Sleeve. The Jack aids in removing Inner Sleeves that tighten up in ball.
