High-tensile fence accessories
Droppers
Droppers are mainly used with high-tensile fences and allow you to space posts farther apart without too much wire sag.
Droppers can be made from fiberglass or polyethylene, and may or may not be set into the ground like a small post. The examples on the right are two typical styles.
The table below shows how droppers increase the distance between posts on high-tensile fences.

| 5 | 50' | 150' | 50' |

| 8 | 33' | 66' | 33' |

Wire tighteners
Wire tighteners are used on high-tensile fences. These small winches are connected at one end of each fence wire to keep the wire tight.
Wire tightness cannot accidentally unwind once tightened and require a special forked handle to operate.
Tension springs
Tension springs are used on high-tensile fences. These galvanized devices go at opposite ends of the fence wire to the tighteners described above to maintain tension.
Some makes of tension springs also serve as tension indicators since they extend a known amount for a known pull. For instance, one make extends one inch for every 150 pounds of applied force.
