ABSTRACT:
A longitudinal live rubber bowling ball insert having the purpose of providing a finger hole which is of a size which more properly matches the finger size of the user and, in which an internal wall portion of the insert is provided with a plurality of grooves, said grooves greatly increasing the "lift" which may be applied to the ball by the user resulting with the bowling ball having a more pronounced hook as it travels down the bowling alley. The insert is angled on both opposing ends, thus enabling the insert to be used in bowling balls drilled for right-handed or left-handed bowlers. The terminating angle is necessary in order that the insert, once placed in the bowling ball, does not extend out beyond the ball surface.
