Insulators polywire

With Gallagher's XDI solution, you know exactly when the insulator needs to be replaced so you always prevent short circuits on your cord, HT wire or poly fence on time. The XDI insulators are cleverly designed to guarantee no shorts and features a handy orange wear indicator to show when the insulator should be replaced. This insulator is easy to secure to posts with its extra sharp point. And also available with bolt-on option, for metal posts.

They come with a 10-year warranty period.
