The Loose Ring allows for immediate release and relief from tongue and bar pressure. The bit is immediately reset to a neutral position in the horse's mouth.
Sara Grills link is 40mm and is designed to sit vertically on the horse's tongue and suitable for a horse that uses its tongue as a means of pushing against the bit to take control. The Sara Grills will cause the horse to draw its head back and tuck its chin in. Providing very little surface are to disperse pressure the Sara Grills is more severe than the Control Plate and the Buster Roller.
