Common Barbed Wire Configurations

In order to attach barbed wire to chain link fencing a special cap with an extended arm is required. A chain link barbed wire arm installs on top of the line posts in order to support the strands of wire. The posts at the end of each fence line, called terminal posts also have to be modified in order to attach barbed wire.

A single barb arm will hold 3 strands of the galvanized wire. Usually at a 45 degree angle, the barbed wire fence is normally pointed outward in order to make climbing of the chain link fence difficult. However, sometimes chain link fence with barbed wire will have the arms reversed and point inward. There are even 3 strand barbed wire arms that point straight up in a vertical orientation. Increasing the overall height of the fence.

Security Fencing with 6 Strands of Barbed Wire

A 6 strand barbed wire arm is a V shaped extension arm that holds 3 strands of galvanized steel wire facing both inward and outward. Adding even more security to a chain link fence with barbed wire. 6 strand barbed wire fences are found where high security fencing is required. Sometimes, coils of razor wire or concertina wire are installed in the center of the V shaped extension arm. Razor wire makes climbing a chain link fence almost impossible without causing serious injury.

Each row of barbed wire is a galvanized strand wire that gets stretched between the terminal posts. Terminal posts for chain link fence with barbed wire are found where each line of fence starts and stops. They can be an end post, corner post or gate post. On long lines of chain link fencing there are extra terminal posts added to the fence line called pull posts. A pull post divides long runs of chain link fence into shorter stretches. As a result, making installation easier.

In order for barbed wire to attach to terminal posts, the fence posts have to be extended and special chain link parts (called fittings) are required. There are two methods of extending terminal posts for chain link fence with barbed wire. The first is to simply install longer posts. Providing enough room to attach the galvanized steel clamps used to hold each strand of barbed wire. The Second method is to install a special cap with an extended arm much like the cap used for line a post. Installation of a corner extension arm or end post or pull post extension arm make it even hard to climb a galvanized chain link fence when compared to extending terminal posts.
