A common residential fence consists of vertical fence boards fastened to a framework of upright posts and horizontal rails. Typically 3 1/2 inches by 3 1/2 inches, fence posts anchor to a post hole or elevated concrete pier. A set of two rails runs between adjacent posts and provides a nailing surface for fence boards. Standard wooden fence rails are 1 1/2 by 3 1/2 inches of lumber, called a "2 by 4," and fence boards typically measure 3/4 inch thick by 5 1/2 inches wide.
Like wooden fence posts, a chain-link fence's tubular, metal posts anchor to a buried concrete footing. A set of tubular rails runs between adjacent posts and attaches to the posts via specially designed brackets. Chain-link fence installers unroll chain-link fabric between the posts, pull the fabric taut with manual or mechanical stretching equipment and bind the fabric to posts and rails with metal clips or wire connectors.
Often applied to agricultural operations, the exceptionally taut wires of a high-tensile wire fence withstand great stress. For large high-tensile wire projects, fence builders sometimes pound fence posts directly into the earth. Alternatively, posts sit within a concrete post hole. As with a chain-link fence, fence builders use special stretching equipment to pull high-tensile wire between posts. High-tensile wire fence posts are typically wooden, and builders commonly secure wire to posts with staples. Because of the wire's tightness, the posts of a high-tensile wire fence often require additional bracing, such as anchor-post assemblies at each corner of the fence's perimeter.
Manufactured from rot-proof plastic, vinyl fencing resembles conventional wooden fencing or picket fencing. Like conventional wooden fence boards, vinyl fence boards attach to a set of post-mounted rails. Most vinyl fence systems are not entirely plastic. Many vinyl fence systems consist of wood or metal posts covered with a vinyl sheathe. Vinyl rails connect to the sheathe via special brackets, and vinyl fence boards, panels or pickets fasten directly to rails with screws.
