The Shires Lunging Adapter is suitable for lunging using a bridle, this adaptor removes the fiddly job of rethreading the lunge line when changing reins. The adaptor lays across the poll, threads through the bit rings and connects to the lunge line clip under the chin. Changing reins is simply a matter of turning the horse around. SupaFleece padding at the poll makes this lunging adapter ideal for sensitive horses.
