Abstract: A portable string aligner for tennis rackets, racquetball rackets, and for other game equipment in which a racket is used. The aligner combines an elongated rectangular base member with multiple spacing pegs removably fitted in a retainer track. The spacing-peg tops protruding externally through a track opening in one surface of the base member are of sufficient length and are shaped to fit through the squares formed by the vertical and horizontal cross-over of the racket strings in a strung racket head. By hand pressuring the spacing pegs through the racket string squares, the racket strings can be restored to proper alignment on the court during pauses in play.
