A simple concept that works. No tools required. No more mistakes in buying the wrong size and less to have hanging around on your tack room wall. Simply twist the shanks in opposite directions and the bit size increases or decreases.
Rubber Mouth Dee Bit with a patent pending design allows you to precisely adjust the mouth size to fit everything from 4-3/4" to 5-1/2".
Note: We advise you to check with your breed or discipline association regarding any bit restrictions for competition and warm up.
