So simple! Take the measuring tool, put it in the end of the shaft you want to lengthen, when it stops look at the color coded dot. It tells you what matching color coded extension will fit in that shaft.
No more measuring! All the extensions are color coded so it's a snap to get the right size quickly. What a time saver!
