The grip tray places the grip in the position where it would be when it is installed on the shaft in relationship to the balance point of the swingweight scale. The picture is not set up correctly in that the shaft should not be right up againist the back edge of the swingweight scale. You would allow a space based on the measurement of the grip cap on the particular grips that your are using. The grip tray comes with a magnetic weight that attaches to the other end of the scale to keep the scale in balance.
