XDI insulator

The XDI (Xtra Durable Insert) is an innovative screw-in insulator. This (patent pending)
screw-in insulator can be used to attach electric fencing wire to wooden posts, while offering a number of special features. Its continuous metal core makes the XDI more robust than any other screw-in insulator. This core is located precisely in the center, and reduces the likelihood of short-circuits to zero.The XDI is also immediately recognizable by its design: black and orange, with the plastic orange section serving as a wear and tear indicator. It signals when the XDI needs replacing, and therefore guaranteeing optimal current conductance..
