To use heavy duty nail-on insulators, simply nail them onto a post and then feed your tape or wire through the simple slots. The angled layout of these insulators makes them suitable for creating junctions when fences are being built in multiple directions, as illustrated in the photograph (right). Rated up to 24,000 volts, these chunky insulators are extremely efficient at preventing any loss of electricity, and when properly set up, they will hold a wire or tape of up to 40mm in width approximately 30mm away from the wooden post. this pack of twelve heavy duty nail-on insulators is not supplied with nails.
