NQN 200 Pcs Black Electric Fence Insulator Screw-in Insulator Fence Ring Post Wood Post Insulator and 2 Pc Free Insulator Socket Tool (Grid System Accessories for Animal Husbandry Electronic)

To be staight I like them for the easy installation. Just drill the holes then screw them in and your good to go. But at any point your pets decides to test them they snap. My 20lb dog stepped through the wire and his paw broke 4 In the line

Needed to hot wire across posts and rails for a cribber. Just make sure the drill used is the right size or the nail will snap off the head. They are amazing and so thrilled with the ease of installation and use.

These are working great. Only issue is that the tool has play in it. I cant get it to work with the hook, it wiggles too much. So I just use my hand. Which is fine for trees. Although its a serious work out.

Works fine,, just make sure to pre-drill your holes before screwing these in . the plastic will strip from the screw if you just try to drive them in.

Time will tell if they last but they installed fairly well with drilling pilot hole. Out of nearly four hundred installed over the weekend 6 separated and I couldn’t get them all the way in.
