ABSTRACT:
A game racket with adustable string tension including a vertically movable tension bar positioned between the throat and handle sections, perpendicular to the plane of the racket, which engages directly to a loop extending below a main string retaining bar by an integral hook. The position of the tension bar and consequently the string tension are varied by rotating an interconnecting tension ring which traverses parallel threaded sections of the outer surfaces of the neck, and which is maintained at particular position by an abutting locking ring.
