ABSTRACT:
A finger hole insert for a bowling ball which is formed of a resilient tubular body and is adapted to be inserted into a finger hole. The insert has a generally cylindrical inner wall surface defining first and second finger openings at opposite terminal ends of the insert which are sized to permit insertion of a bowler's finger therein. The first finger opening has a thickened arcuate finger pad therein adapted for cushioning the bowler's finger. The second finger opening has a plurality of ribs extending in longitudinal spaced relationship around its inner periphery adapted to augment the spin and lift applied during delivery of the bowling ball. In this manner, the bowler has a preferential choice between the function provided by each finger opening of the insert. In another embodiment, the first opening may include a textured gripping surface.
