The Anchor Form is designed to hold about 250 pounds of concrete. After your cement is set, you can tip it up with a 2 x 4 or the hand grips conveniently located on the bottom at each side. Once it is on its end, the anchor can be rolled to its destination. The molded hole allows an easy connection of your chain thru the middle.  Dock builders can fill many forms in one cement delivery, or one at a time on site with 3 x 30kg (66 pound) bags of cement. Sold individually.
