Softball Baseball Training Device

After seeing how expensive an RMT Club is I thought I would design my own version that slides on to a short children's bat from t-ball. This is designed to fit on a 2-1/4" softball bat so a baseball bat will work but it will sit up higher on the barrel due to the increased diameter of a baseball bat.

The plug is designed to allow the user to add or remove sand or any other weight shifting material so they can change the weight of the device. The original RMT Club comes in four different weights.
