This correction bit is made with durable stainless steel and features copper bars to promote salivation. The stainless steel port and long cheeks are multi-jointed so that each side can be worked individually, allowing for more subtle cues. Rein action with this bit applies pressure to the tongue at the port joints. A helpful bit for trained horses that need precise feedback. The addition of a curb chain to this bit can help increase speed, rating, and stop.
