Compression spring standard 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
• Standard tension (silver) spring which can tension 1.2 mm wires
