A very unique clamp constructed of strong galvanized steel to help prevent the animal from swinging its tail. Finger operated to easily set onto the tail shaft of cattle. It is designed with two protruding buttons to the inside of the clamp that, when applied, press against the tail shaft and create pressure points against nerves causing the animal to hold the tail more still. A great tool to use when clipping or fitting. Length of clamp is 5-1/2”.
