Batting aid
Abstract:
A batting aid that may easily be installed upon fixed or temporary structures, made up of a main frame that slidably supports a tube which in turn supports a ball for a batter to hit. The ball is fixed to the tube by a wire cable that extends through the ball, and is in turn mounted to the tube. The tube is height adjustable so that batters of differing stature and ages can easily practice upon balls at varied heights. The assembly is strong in construction so that a practicing batter is able to hit the ball hard and not cause damage or require another player to throw balls over the plate or return balls to the batter.
