Gallagher - Heavy Duty Tension Spring 

A versatile product that can be used inline or at the end of a fence, with built-in surge protection. The tension spring compensates for expansion and contraction of the wire caused by temperature fluctuations and keeps the fence wire evenly tensioned during summer and winter.

Maintaining tension on the fence wires also prevents excessive tension on the end or corner posts, reducing maintenance costs.

• Allows the fence to withstand snow load
• Ideal for permanent fencing where livestock pressure requires flexible fencing
• Can be used as a tensioner for short lengths of fence
