The Draft Hoofjack® is for use on hooves larger than a size 7 and consists of one standard base with  two magnets, one draft cradle, and one straight post with draft rubber cap. If your draft horse is unshod and you are uncertain of it’s shoe size, measure across the widest part of the hoof. If the hoof is 7 3/4″ or more in width you will need to order the Draft Hoofjack®.
