Medium twisted sweet iron hinged port with copper rings. 8" cheek 5" mouth and 2" port height. This nice stainless steel cavalry shank is not only eye appealing, but very well balanced. The unique ball design will prevent pinching on the corners of the mouth found in most traditional bits. The mouthpiece is designed to get more response out of the horse with less effort from the twist on the bars and the higher port. It will provide more leverage, control and stop. The copper adds moisture and softens the mouth while the rings pacify a nervous horse.
