The Schneiders FES Copper Twisted Wire D Ring Snaffle Horse Bit is designed to offer control when you need more than a standard snaffle. The twisted wire design puts balanced pressure on the tongue, which allows for easy swallowing and comfortable wear for your horse. The bit provides optimal poll pressure to help you achieve the desired head position. The copper mouthpiece promotes salivation and increases sensitivity, encouraging better communication between you and your horse. Finally, the 3 1/4" stainless steel rings are hinged and pinchless, ensuring your horse's comfort. Mouthpiece: 5", Bit diameter: 3/8".
