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 commonly utilize top horizontal rails, although this is not always required if the terminal posts are securely braced. A top tension wire can be used in such situations. Bottom rails may be added instead of bottom tension wires, and for taller fences (10 feet or more), additional horizontal rails are frequently incorporated.
