Insulated Ratchet Wire Tensioner
This is an insulated version of the Ratchet Wire Tensioner. There is an insulation block built into the fixed part of the strainer and the ratchet will provide electric wire with the necessary tension.
These are suitable for using on wire fences and are perfect for ending off perimeter fences as the insulation block allows them to be tied directly to a strainer post without losing power.
