An apparatus for use in stringing rackets comprising a support structure including a pedestal having a base portion with a weighted foot pedal pivotally attached thereto, a racket supporting portion attached to the upper end of the support portion, a string clamp mechanism operatively connected to the foot pedal, the clamp mechanism including clamp members for engaging and clamping a length of string extending therebetween, a clamp support member mounted adjacent to the racket supporting portion, a string clamp assembly including a pair of members having portions for engaging a length of string extending therebetween, a member pivotally connecting the pair of members, a spring between the clamp members biasing said string engaging portions apart, and a clamp operator member movable between an open position whereby a length of string can be moved between the string engaging portions and a closed position in which the string engaging portions move into clamping positions. The subject improvements also reside in an improved string tension adjustment mechanism, a novel guide bar assembly for supporting the string clamp assemblies in different positions, a novel brake assembly for locking a racket in different positions relative to the string clamp mechanism, a novel racket engaging support structure including a quick operating racket clamp and racket release device therefor, and an optional modified clamp support structure which enables stringing rackets that have their crossed string reaches oriented at other than a right angle.
