The unique design of this bit offers direct contact similar to a ring snaffle with the shoulder elevation of a gag and the collection from a curb strap. This is a great training or transition bit. The gag movement allows the horse to give at the poll before the curb comes into effect. All of these bits should be adjusted to fit with one wrinkle in the horse's mouth and a loose curb strap to allow 2-3 fingers. This mouthpiece will apply more pallet and bar pressure and is an excellent all purpose mouthpiece which will work well on most horses. Sweet iron keeps a horse's mouth moist.
