Abstract

Abstract A racket handle cap is of a pliant material in single piece injection molded construction and comprises an opening at one end therefrom elongately extending along a grip portion to a flaring section to define an internal cavity, an adhesive tape and a plurality of counter weights. The grip portion has a plurality of oval are circulation vents and circular air circulation vents which ae respectively formed in rows for eliminating the air therethrough by inserting the handle part of a racket frame thereto. The counter weights respectively conform in shape with the oval circular air circulation vents for defining their optional and removable insertion to the oval and circular air circulation vents, whereby the weight adjustment and distribution of said racket handle cap being achieved.
