The Robart Pinchless Spinner Ball Port Snaffle is a revolutionary bit designed to help horses relax and stay focused during training. Its unique design allows each side of the bit to be worked individually, giving you precise control during schooling. This revolutionary design eliminates pinching of the tongue and cheeks, providing ultimate comfort for the horse. The bit features a copper inlay that promotes salivation and increases sensitivity in the mouth, contributing to a more effective communication between horse and rider. The low port features a 'spinner' ball center, which further aids in helping horses relax. This bit is not just a tool, but a contribution to a more productive equestrian experience. Mouthpiece: 5".
