Accurately measure the tension of your wire fence with the Zareba® Large Fence Tension Spring. This conductive spring can absorb pressure on your fence and maintains fence power while it's in place. Get visual feedback of the tension the wires and keep your fence strong and secure through all seasons as the spring reacts to the expansion and contraction caused by changing temperatures.

This large fence tension spring allows you to run longer distances between posts. Use one tension spring with each in-line strainer. Since the spring is made from a conductive material, it allows for uninterrupted power to the fence.
