Cow Trainers are used in the stanchion barn where they are connected to an electric fence charger to give cows a slight shock when they hump to evacuate. Cows are soon "trained" and the stanchions stay much cleaner. Galvanized Notch Bar Trainer has points at a 98 degree angle for better penetration without any sharp edges. Uprights are cadmium plated and equipped with Magi-Klips and insulators.
