These insulators just nail onto a wooden fencepost and have the wire or twine slotted into the top in order to be held securely. They are similar the staple electric fence insulators but with these, it's possible to release the wire or twine from the top, move the insulator or post then reattach the conductors without having to thread the whole lot through or removing the insulator.
They only have enough space for holding wire and twine and like the staple insulators
, are suitable for short to medium electric fences and for use with smaller energisers. Larger fences / energiser should use our nail & leather insulators.
