Zareba ITRXB-Z 5-Inch Snap-on Reversed Insulator, Black

What I needed and it worked

Product arrived quickly. Product did it’s job

Bought these to keep my dog from climbing the chain link fence like a ladder and escaping.I did find that certain imported T posts are hard to fit these insulators onto. It seems the spacing of the nubs on the posts are closer than US made posts which makes it harder to get the insulator to snap in place.I hope the UV resistance of the plastic is high so these will last awhile.

Worked as expected.

We found that the ends snap off. My husband finally came up with a process of using screwdriver and pliers to twist around post. My brother in law heated the end with grill lighter, spread the end wider so they would pop on without force. Either way they required a lot of work. They are bad design. Just a little wider space on the end makes all the difference.

Good standoff, though may snap easily under 1500lb cow scratching.

After installing these alongs the fence they started to break apart at the seam along back of tpost and fall off. Several different bags (batches), same result. Now replacing with different product. Waste of money and time.

I have had problems with them popping off on the wire side of the T-post when an animal rubs on them. If I actually had my hot wire on all the time this may not be an issue.
