Abstract
A sports racket having a protector strip wound around the frame thereof in a helical path. The strip is passed between the strings of the racket with each convolution and is held in position by virtue of a set shape and the resilient or plastic memory characteristic of the strip. Preferably the set shape is a tubular helix of lesser diameter than that of the racket frame cross-section.
