The versatile design of the post insulator is easily installed and compatible with a large variety of wire types and thicknesses.

  • Fence insulators hold the wire 1 in. from wood post to make sure energy is not lost
  • Compatible with steel, aluminum, and high-tensile wire gauges 9 to 22
  • Supports poly wire and poly rope up to 1/4 in. in diameter
  • UV-stabilized polyethylene construction gives the post insulator durability
  • Included nails make installation easier
  • Simply press the electric fence insulators at the desired height and tap the nail into the wood post
  • Pack of 25 for greater coverage

Q: I would pay three times as much if these didn’t break or start arcing at the seams within a few months. Why doesn’t Tractor Supply have an alternative that is maybe more expensive but actually works for a while?

Q: Can these be used as corner post insulators?

6 years ago
1 Answer
  • A: We do not recommend using this in-line insulator as a corner post insulator, as this product is not designed to hold the proper amount of tension for the wire at a corner point, and the wire could potentially become damaged or slip out of place.

Not durable.

Do not last long very long, get brittle, in a short period of time.

Thank you for sharing your experience with the American Farm Works Wood Post Knob Insulators. We’re sorry to hear they became brittle sooner than expected. These insulators are designed for durability when properly installed, so making sure they are mounted securely and not over-tightened can help prevent stress that may lead to cracking over time.

Easy to work with

These were so much easier to deal with than the screw in type. There are stand-off tabs on the bottom that hold them in the position you prefer. Great value for your money!

DO NOT BUY

these insulators degrade within one year. I have well over 5 hundred I need to replace. the time to replace it is not just the wasted money but the wasted time. i have over three miles of fence to maintain and I would like to not have to constantly have to replace insulators. if you read the reviews on the web site they try to say it was a bad batch but the poor reviews span many years.

No, I do not recommend this product.

We appreciate your feedback regarding these insulators. Stocking and supply chain systems mean there can be product from a wide range of years sitting on the shelves for an indeterminate amount of time. Our insulators are covered by a 1-year replacement policy for manufacturer defects. Please contact us at 855-592-7322 with any questions!
