Designed by us in a way that the wire, poly wire, tape or rope goes in on an angle and when strained is secured tightened and unable to extrude out These offset ring insulators will accommodate various types of plain wire, poly wire and poly rope and small electric tape. Simply slide your wire, poly wire, rope or tape in for a neat and tidy tight professional finish. Can be used as high or as low as you like, as long as it is not shorting out on the ground. Need more information or not sure please contact us we have years of farming experience and we are only too happy to advise you. Regards Wayne & Leah
