The Schneiders FES Ported Barrel D Ring Horse Bit is an outstanding bit for both intermediate level horses and seasoned, finished horses. Made of stainless steel, it features a wide low ported barrel and larger D Rings with hooks to offer different leverage options. The barrel applies downward pressure on the tongue, providing relief as soon as the horse bends at the poll. The bit design allows each side of the mouth to work independently, making it a valuable tool for equestrian skill evolution. Mouth: 5 inches. Rings: 3 1/2 inches. Port height: 1 inch. Bar diameter: 10mm.
