Tension bars are used to slide into the fence fabric vertically, and connect to the terminal post by using a tension band. On a chain link fence, one tension bar is needed per hookup for each terminal post (end post, corner post and gate post). Tension bars are also necessary for a gate upright. Each gate requires two tension bars.
Requires tension bands (amount of tension bands needed is one less than height of fence) 6ft high fence typically uses 5 tension bands
