This tensioning accessory offers many advantages by using fencing to help safely restrain cattle and other livestock. It is trusted by ranchers and farmers for proper tensioning of fence lines. The wire tensioner has a screw-in mechanism that easily tightens the wire/rope and maintains the desired tension. Tensioners are weather-resistant and strong enough to withstand the wear and tear of extreme weather conditions. [Application]This electric fence insulator chute can accommodate wires without causing energy loss. Electric fence ring insulators are suitable for use with gauge 8 to 30 high tensile steel wire, multi-strand wire, high tensile steel wire, aluminum wire, rope and electric fence tape. They can be used as start, end, corner or line insulators and are suitable for low impedance applications. and standard load gate controllers. [Easy to Install]The upgraded self-tapping design can be easily screwed into the wooden fence by hand without any technical knowledge.<br><br>NOTE: These insulators are also suitable for most electric fence energizers and fence ring posts and are primarily used to prevent electrical shorts between wires and fence posts.
