I have not used these but just in time to redo the wiring on 3 of my work trailers and 2 boat trailers (bernese mountain dog at 6mo chewed every wire she could find) a small price to pay for such a great guard dog & protective of children and livestock..
Anyway, I will order these and give them a try. Also going to bury the wires in ¼ pvc this time.
