The Nemtek 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.

The compression springs offer the following 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 compression springs are available in

• Standard tension (silver) spring which can tension 1.2 mm wires
• Medium tension (gold) spring which can tension wires up to 1.6 mm.
