Cap suppliers specify the draw height of the caps they supply. In order to meet the given specifications the cap draw height must be measured. It is difficult to measure the cap draw height with a vernier, often producing different measurements and consequently, different results. In cooperation with a leading cap supplier in Australia the digital Redraw was developed. Simply push the foot of the gauge on the cap and the indicator shows the draw depth. This ensures the cap draw height can be measured correctly, quickly, and easily.
