Top horizontal rails are used on most chain-link fences, although not necessary if the terminal posts are braced correctly. A top tension wire may be used in this situation. Bottom rails may be added in lieu of bottom tension wires, and for taller fences, 10 feet or more, intermediate horizontal rails are often added.
Chain-link fences typically use top horizontal rails, although this is not always necessary if the terminal posts are securely braced. A top tension wire can be used in such cases. Bottom rails may be added instead of bottom tension wires, and for taller fences (10 feet or more), additional horizontal rails are often installed.
