West Coast Classic Sweet Iron Port with Roller " Cheeks, 5" Mouth. A favorite of Reiners and Reined Cow Horse Riders. The combination of shank and mouthpiece enhances the horse's topline, stabilizes collection and keeps the horse square in the bridle. Reinsman's Golden Glide bushings enhance the independent movement of the shanks allowing for very stable shoulders. The 2" Solid Sweet Iron Port is curved providing both tongue and palate relief while the notched copper rollers help calm the nervous horse. The combination of the sweet iron and copper encourage salivation making the bit more acceptable to the horse. Copper is a soft metal, check for signs of wear before every use.
