Abstract
A racket for tennis or like games utilizing one or more weight straps, preferably flexible, that are detachably fastened to the frame head by strings in tension for easy weight and balance adjustment by users in accordance with subtle difference in personal preference and to provide a safe weighting device which is unlikely to detach and cause accidental injury during use of the racket. The weight straps consist of a plurality of unit sections that are separated by spaced notches. The spaced notches permit a portion of the weight strap to be severed from the rest of the weight strap so as to allow variable weighting of the racket. The unit sections of the weight straps have holes located therethrough that are aligned with the string holes in a racket. Thus, the weight straps are held in place on the racket through the strings which pass over the weight straps. Additionally, the weight straps include a longitudinal groove for seating the strings and can also include an elastic plate that extends transverse to the longitudinal groove for seating the string.
