Double Torsion Springs

As their name suggests, double torsion springs are nothing but two torsion springs combined together to form one single spring. The most characteristic feature of double torsion springs is that they have two coils. One coil is wound in a clockwise direction, whereas the other is wound in an anti-clockwise direction. Both these coils are bridged in the middle of the spring. Double torsion springs are strong, and have the capability to exert greater force. These springs are capable of generating a total force, which is same as the forces created by two individual springs together.
