TENSION SPRING
Manufactured from your drawing or sample as a one off or large production run, available in a wide range of materials and finishes. It should be remebered that most extension springs failures occur in the area of the loops or hooks. To maximize the life of the spring, the path of the wire should be smooth and gradual as it flows into the end.
