The first fully interchangeable Urethane Thumb insert that requires NO
hardware for installation or any type of tool for changing the insert;
making it quick and easy for bowlers on the go.
This product is of two-piece construction that consists of an outer sleeve
permanently glued into the thumb hole and a removeable grip which loc’s
into place.
The grips are inserted by the bowler within seconds by pushing into the
sleeve and turning until it “clicks”. Catering for the ever changing thumb,
swelling or shrinking between games or even between frames.
As a result the bowler obtains optimum release of the ball increasing
the chances of improved scoring where it counts most.
