Also called extension springs, custom tension springs provide extended force when the spring is pulled apart from its original length.

A flat tension spring is a spring that works by twisting its end along its axis That is, a flexible elastic object that stores mechanical energy when it is twisted. When the custom made spring is twisted, it exerts a torque in the opposite direction, proportional to the amount (angle) it is twisted.
