ABSTRACT:
By using two different diameters at the two ends of each bowling ball finger hole insert or grip, the number of finger inserts required to be stocked is reduced from about ten to about five. At least two ribs are provided in each half of the insert, with the cross-section of the insert being substantially D-shaped where the ribs are located. The inserts are sufficiently flexible so that one edge of the insert may be displaced relative to the other edge so that the inserts are substantially flush with the surface of the bowling ball as the inserts are glued into place. The edges of the gripping ribs have sharp corners to insure good frictional engagement between the fingers and the inserts.
