The Nemtek ES-CNT compression spring standard and medium tension 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.
- 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
- Standard tension (silver) spring which can tension 1.2 mm wires
- Medium tension (gold) spring which can tension wires up to 1.6 mm
- Stainless steel compression springs
- UV stabilised nylon inner
