Zareba Wood Post Screw-In Ring Insulator (IWSIRB-Z): During the first trip to our local Tractor Supply store we looked over every electric fence insulator on the shelf. After a lot of time and consideration we left with several bags of Zareba Ring Insulators that came with 25 per bag for a price of $12 dollars. These insulators were the screw-in type with a hard plastic ring, very versatile and can be used with 9 gauge through 22 gauge high-tensile
steel wire and aluminum wire, all polywire (both regular and heavy
duty), and polyrope up to 1/4-inch in diameter. Since the majority of our fence posts were wood we felt like these were the best choice in durability, aesthetics and versatility for the cost. Other choices were the nail in style insulators by Fi-Shock and Zareba at about half the cost of the ring insulators we bought. Cost is always a big consideration, but we chose to spend a little more on the insulators in hopes that it would save maintenance time down the road.
Review: Our small farm fence has been up and in operation for about a year now. The Zareba Ring Insulators have seen all kinds of weather, including ice storms, strong winds and 100 degree summer days. The insulators have helped keep our hogs, pigs and chickens in and at the same time keep foxes and coyotes out. The Zareba insulators has proven to be a durable product so far with only a hand full breaking when limbs or crossing deer have hit the wire. They are easy to install by drilling a quick pilot hole and simply screwing in. The only area we had trouble with them were in the corners. Initially we did install these insulators in the corners and with stretched wire they were prone to break. These insulators are not made for the corners where electric fence wire is stretched, save yourself some time here. Other than not using them for corners we'd definitely buy and use this product again.
