Extension springs are springs that attach to both ends of other pieces. They store energy and exert a pulling force. When the spring is extended, the force stored in the body is transferred to the mating components through the hooks or loops. Furthermore, extension springs actually soak up and house energy, to create a resistance to another pulling energy. It’s the initial tension that ultimately determines how tightly together the extension spring is wound.
