![HUMP MOLD 15"](http://psh.ca/cdn/shop/products/TMH15_{width}x.jpg?v=1590633066)
15" dia. x 2.5" deep. Fit onto standard 10" centered wheel head pins. Simply lay a slab of clay on top of the hump mold. Think of it as throwing the backside of a form. You will still have to throw a foot by gathering clay from the slab or by attaching a coil and compressing it to the back.
