See Tension at a Glance These springs make maintaining fences a breeze. See at-a-glance how much tension your posts are exposed to. One inch of compression on the spring equates to 150 lb of tension on your wires. This large fence tension spring works with high tensile electric fences and can protect your fence for many years.
Strong Wire
Will Not Rust
Reduce the Strain on End Posts Use a Zareba® Fence Tension Spring to protect your fence wire from damage caused by over-stretching. The spring keeps the fence wire at a steady tension, compensating for any expansion or shrinkage that may occur due to the weather. The spring buffers fence posts from tension too, helping to reduce maintenance costs.

Benefits and Considerations of High Tensile Fencing

High tensile fence is an excellent choice to safely contain most species of livestock, including various exotic species. It is also equally effective keeping unwanted predators, deer or other wild animals out.

High tensile is an affordable, low maintenance permanent perimeter fence, lasting over 40 years. It works as a simple barrier fence or can be electrified for greater effectiveness and animal safety.

The key to a successful high tensile fence installation is advanced planning, combined with proper tools and quality materials.

We recommend Zareba® high tensile components, which are rugged, reliable and designed to withstand harsh environmental conditions, providing long life for your fence.

Zareba® has developed high tensile videos to help design and build your high tensile system. Once you build a high tensile fence you won't want any other type of fencing system.


Expert Tips


Posts for High Tensile Fencing

Because the distance between posts in a high tensile system can be 30’–90’, and the wire is under tension, wood posts are recommended.

Line posts should be a minimum 4” in diameter, with 6-8” diameter posts used for corner posts and gate posts. In some cases T-posts may be used for line posts.

High Tensile Line Post Insulators:

We recommend either pin lock or tube insulators for high tensile fence systems. Both allow the fence wire to move as needed.

High Tensile Corner & End Post Insulators:

  • Wrap Around Insulator – Slide wire through tube and wrap insulator around corner or end post. Secure with 2” barbed staple. Durable polyethylene with poly insert for added strength.
  • Donut Corner Insulator – made of unbreakable polycarbonate, extremely strong with 5,000-lb. tensile strength.
  • High-strain Corner Insulator - made of fiberglass reinforced nylon, engineered for full tension of 200,000 psi wire.
  • Porcelain - very strong


How to Electrify Your High Tensile Fence

If electrifying your fence, you need to make electrical jumper connections between all electrified fence wires.

Use a length of 12 1/2 gauge wire as a jumper and connect it to a hot wire with one of the extra crimping sleeves placed on the “hot” fence wires prior to tensioning. Crimp to attach.

Then slide a section of insulated plastic tube, or insultube, over the wire to prevent it from touching the non-electric wires. Crimp.

Repeat until all electrified wires are connected. Next, install and connect your electric fence charger to the fence.
