Adjusta Bits have a patent pending design that allows you to precisely adjust the mouth size to fit everything from 4-1/2" to 5-1/2".  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 descreases.  No tools required.   A simple concept that works.

Our line of Miniature Horse Bits includes styles to fit a wide variety of needs.
