Designed for a well-trained horse to comfortably carry all day, the headstall ring aligns the mouthpiece at a pleasing angle and prevents downward rotation when rein pressure is applied and the Golden Glide bushings ensure smooth movement and a no pinch design. The 3-Piece snaffle with a copper roller is great for a busy mouthed horse. Sweet iron and copper promotes salivation and combined with the overall design encourages relaxation of the jaw. This is also a great choice for the nervous or busy mouthed horse, or when you want a more direct signal than you get with a loose ring snaffle. It applies pressure to the horse's cheek on the opposite side of the face from the rein you pull to allow for better flexion.
