OZCO Oz-Post is a fast and easy instant post hole system that uses high-quality, steel post anchors to install wooden posts or fence posts without a mess from digging or pouring concrete. It consists of an intelligent post anchor design that prevents wood from premature rot and weed eater damage. Oz-Post Post Anchors are installed using a sledge hammer, OZCO Manual Driver Kit or the OZCO Jackhammer Driver Kit. An Oz-Post system is great for installing temporary or permanent fencing, mailboxes, clotheslines, playground equipment, street signs, decks and more.
