Shipping charges don't make sense. By Cathy

Love the insulators. The shipping charge on the two packages I purchased was $3.00. I thought this was reasonable. When I tried to add a 3rd package, the shipping charge jumped to $19.00! That's crazy. So, I just stuck with the two packages.

Really Cool Device By Bill

I have a small garden w/ just corner posts (no intermediate support) and I use small stainless steel springs to indicate tension. These little tighteners are just perfect to set the tension from my initial installation. Simple, elegant design that flat out works like a charm. Easy to wind up or slack off as little as a half turn. Appear to be well made of thick, sturdy plastic. As an engineer my hat is off to the guy (or gal) who designed these little gems!

Tightened our fence By RAK

Used a few of the poly wire tighteners to tighten up our fence that get stretched out from snow coming off the barn roof. It only took a few seconds and the fence is now at the proper height.

simple and effective By Rick

I installed several of these in horse fields with horses of different ages. The younger horses mess with everything and the older horses don't bother anything. The tensioner is very easy to use and usually doesn't need more than one twist if fence is installed tight the first time. Not sure how they will hold up to the southern Arizona summer, but we'll see.

Awesome! Exactly what I needed By Cat

They were a little smaller than it seemed on the picture which was perfect for me. I put one on all 5 wires in several different places. They are lightweight and don't drag down the polywire. It also worked well on the one thin metal wire. Glad I bought them, but wish I had I had bought two bags instead of one.

Ease of Use By Holly

Very easy to use wire tightener. The best part is that it can be used after the wire has been strung. Unlike another wire tightener that required the line be fed through the device - so either you planned ahead (we didn't) or you cut the wire, feed it through the device, tie the wire back together and then hope that the knot doesn't impinge on future tightening (it can). So for the same price, we'll stick with these tighteners in the future.

Q.Will this tightener work for 1/4" poly rope? IF not what would you recommend? thanks

This product is designed for poly wire. At this time, we do not have a tensioner for poly rope but have shared the feedback with our Product Managers. We recommend hand tightening the fence.

Q.Will this work for Poly Rope as well?

This product is recommended for use with poly wire only.

All About

All About Polyrope

Electric fence wire conducts the electric charge from the fence charger around the length of the fence. Position one electrified wire at animal’s shoulder height; this will cause it to touch the fence with its nose, making it back up.

Wire types include smooth steel wire, aluminum wire, high tensile wire, polywire (stainless steel wire strands woven with polyethylene) polytape and polyrope. Your selection will depend on the type of fence, the type of animal you are containing and how long the fence will stay in place.

Polywire, polytape and polyrope are good options for temporary, rotational grazing or to be used along the top of a fence as they are more visual for animals such as horses. For a permanent perimeter fence, you should use steel or aluminum wire.


Features and Benefits

  • Highly visible to animals
  • Lightweight
  • Wind passes through, low wear & tear
  • Convenient to install and repair
  • Will not rust

Ideal Uses

  • Excellent for horses
  • Temporary fencing
  • Rotational grazing
  • Equine fence kits

Polyrope is an excellent high visibility choice for your fence line. It is stronger than poly wire, with stainless steel strands woven through the rope.

The steel strands ensure maximum electrical energy is carried through the fence line at all times. Use a splicer to maintain a good connection. Most polyropes are about 1/4 inch in diameter.

Note: For best results, use a low impedance fence charger to energize polywire and polyrope fences. Polyrope should not be used with continuous output chargers.

Expert Tips


The height and spacing of the wires will vary with the animal you are containing. Position one electrified wire at animal’s shoulder height; this will cause it to hit the fence with its nose, making it back up.


Poly wire is lightweight, so it is very easy to handle. You can rewind it very easily, move it and re-use it. Splice poly wire by tying a good, tight knot to maintain connections. Use a poly wire line tightener on each line and each side of the fence to maintain wire tension.


Fence Wire FAQs

Q: Why is poly tape better for use with horses than regular wire?

A: It's a matter of visiblity. Horses can see the tape more readily than wire. Remember, electric fencing is a psychological barrier: after a horse has met up with a poly tape electric fence and has felt the shock, when it sees the poly tape again, it will remember the shock and stay away from the fence.


Q: Why should I place one wire at the animal's shoulder?

A: Positioning one electrified wire at animal’s shoulder height will cause the animal to hit the fence with its nose, making the animal back up. See illustration below.


Q: Won't poly tape succumb to wear and tear?

A: Poly tape is designed to withstand wear and tear. The open-weave design allows wind to pass through it, reducing wear and increasing longevity of the fence. However. logically poly tape will not last as long as steel wire.


Q: What kind of fence wire do I need?

A: Generally, use the most highly visible fence wire you can afford -- for the simple reason that animals can't avoid a fence they don't see. For horses, many owners prefer polytape in conjunction with steel wire. For other animals, yellow and black poly wire may do. And high tensile systems require high tensile steel wire.
