“The screw-in insulator is a good idea but needs to be improved upon to make them truly strong and versatile. They will work fine on straight runs but question them on any up or down slope. Hi-tensile puts a lot of strain on them in these cases. The screw should be longer and have a greater diameter and the metal inside the insulator should also be thicker.”
“These insulators go in easy, look nice and hold the fence well ( even in corners). I highly suggest buying the drill attachment, It makes the task of installing the insulators much simpler.”
“Bought a few packages to put an electric fence around the chicken coop to keep out raccoons - easy to use as the have a clever angled slot for the wire making it easy to run”
