Zareba T-Post Poly Tape Insulator for Electric Fences - 25 Pack - ITTY-Z, Yellow Insulators - Easy to Install Electric Fence Insulator, Includes 25

I used these to secure poly tape to T-Posts. They worked really well, they snap onto the post very firmly and securely hold the tape vertically (though it can slide through to tension it). The only issue I had was when I tried to extend my fence line is 40 degree weather - they are quite hard to snap on when they are cold. I moved a few into an inside-my-coat pocket and that was better, then decided to warm them in a small bucket of hot tap water and they snapped in even easier. They have been holding up well over time.

Easy sturdy and easy to use. Deer kept breaking down my thin wire electric fencing. They couldn't get see it at night and got hung in it breaking it down. I decided to put up horse ribbon which is much more visible. I chose these hangers because they were the most economical to use with tee posts. The installed easily and after several months they continue to hold up well. I haven't had to replace any of them. The deer can see the horse ribbon at night and jump over without breaking it down. I probably won't by again unless i put up new fencing somewhere else. These show no signs of weathering or wear.

Does the job well. No issues when installing fencing.

These are good. Always worth the money. I could buy these all day. They last a while but these ones seem to last longer these are super easy to use and are the best for electric rope. These are the best when it comes to proper functioning of electric fencing.

Good and sturdy

I buy these for running deer fence around vegetable farm. I use a mixture of poly tape and wire. These insulators will handle both. My hands aren’t as strong as they used to be so I use a 6.5” set of channel locks to install them. They’re built tough enough to hold under a tight strain and I’ve got some that have been used in multiple places over the years. The only time I’ve broken them is when I leave them on a post and throw them on a trailer. They do t like that at all.

Very easy to get on the posts. If you’ve done this before you know some brands are very tight/stiff and hard to wrap around.

I really like the design of these insulators, but the plastic seems to have an issue with cold weather. They performed well until our temperatures dropped down to around zero (Fahrenheit), and the wind kicked up a bit. About 10% of these insulators snapped/broke off of the t-posts in the wind and cold. They were fine in high winds before it got really cold. Catching the wind was 1.5" fence tape. Our fence has about 800 insulators of various styles. This style was the only type that broke during that bout of relatively harsh weather, causing me to have to go out in that weather and perform fence maintenance. Many of our other insulators, which did not break, are well over 10 years old. These insulators are also more difficult to install on a t-post than any other insulator I've used. They require a screwdriver (or similar tool) to help them bend enough to be installed. Perhaps that is what weakens them. If so, that is a pretty significant flaw.

Not sure if they make smaller sized metal R bars now but these are almost impossible to get on...need a man and a pair of pliers..Once on they sure aren't moving !!!.....so make sure they're put at the height you need them at !! ....They fit super tight...Bought 4 bags...going to return 3...too hard to get on the T bars I have.
