Compression spring - heavy tension electric fence

The Nemtek compression springs heavy tension (15kg) is used to maintain a constant tension on the electric fence wires. Wire tension on an electric fence will vary over time and the springs will maintain a constant force on the electric fence wires to keep them neat.

Features:
• A nylon plastic inner which eliminates galvanic reaction between dissimilar metal thus reducing rust and increasing the life of the wire
• Can be used with any type of Nemtek electric fence wire
• The heavy tension compression springs (15kg) can tension wires from 1.6mm up to 2.0mm.
