A chain link fence is a type of woven fence usually made from galvanized steel wire. The wires run vertically and are bent into a zig-zag pattern so that each "zig" hooks with the wire immediately on one side and each "zag" with the wire immediately on the other. This forms the characteristic diamond pattern seen in this type of fence.

In the United States, fencing usually comes in 20 rod and 100 ft. rolls which can be joined by "unscrewing" one of the end wires and then "screwing" it back in so that it hooks both pieces. Common heights include 3', 42", 4', 5', 6', 7', 8', 10', and 12', though almost any height is possible. Common mesh guages are 9, 11, and 11.5.

The popularity of chain link fence is due to its relatively low cost and ease of installation. One drawback, however is that due to the open weave, chain link fence offers little privacy. This can be slightly improved by the insertion of slats into the mesh, but not completely eliminated.

The installation of chain link fence involves setting galvanized steel posts into the ground and attaching the fence to them. The posts are nothing more than sections of tubing and can either be driven in or set in a hole full of concrete. End (terminal) posts must either be set in concrete or ancored to prevent leaning under the tension of a stretched fence. After the end posts are set, line posts are driven in equally spaced at intervals of 8-10'. The fence is then attached at one end, stretched, and attached at the other; the excess being easily removed by "unscrewing" a wire. Finally it is tied to the line posts with aluminum wire.

Chain link fence recommendations

• An optional tubular top rail to help prevent bending of wire tops
• Setting line posts in concrete every 50'
• Fasten fence to end posts using tension bands and tension bars.
• Bottom wire to deter animal digging and pushing
• Stretch fence and wire with a ratcheting tension tool (comealong).
• Use a post pounder or driving cap to help prevent deforming of post tops.
