Posts, poles, columns and other vertical elements are made of steel and other metals, as well as wood, plastic and composite materials. Such vertical elements must be supported by some sort of footing to resist pressures of wind, shifting ground, frost heave, and other forces. Even a small gate post needs anchoring to stay plumb and solid, or it may sag drag and not latch properly. This guide provides an alternative to the use of concrete for the purpose of supporting the vertical elements of fence and gates. Over 100 years ago, Anchor Fence determined an alternate to concrete was needed. Using the tree and its roots as a model, Anchor established a stabilizing system consisting of steel anchors. This system is commonly used in North America, and has been approved by over twentty state transportation departments.
