Tension Bands are used to attach chain link fabric/mesh to a terminal post, corner fence post, end fence post, gate fence post or gate frame pipe Tension Bands Wrap Around the Pipe on the Fence and Attach to a Tension Bar Holding the Fencing. As a Rule of Thumb Use One Less Tension Band per Stretch than the Height of the Fence (Example: 4 ft. Height Chain Link Fence use 3 Tension Bands)
