7 inch Cheeks, 5 inch Mouth, 2 inch Port. Sweet Iron Broken Port. This bit is designed for the middle aged competition horse. 1 inch gag action with the new "no pinch" ball hinge. This bit will help you gain rate and turn on a hard running horse. I like this bit for running advanced horses on bigger patterns where I need to be able to rate them for a turn. This bit will help you gain confidence in your turns on a horse that has not been turning well. Medium to Maximum Control.
