Replacement insulator for pigtail posts and discontinued zig zag post. The insulator has a 9mm diameter hole specifically designed to be used in conjunction with Hotline metal posts. Suitable for polywire, galvanised wire and rope up to 7mm and tape up to 12mm.

Other information: The insulators primary role is to securely hold the fence line without power leaking from post to ground. A well designed insulator will hold the line securely so that it will not wear the tape, rope or wire when buffeted around by the elements or will allow the line to freely pass through without the impedance of sharp edges.
