Custom Stainless Steel Wire Pull Spring
EXTENSION SPRINGS are attached at both ends to other components. When these components move apart, the spring tries to bring them together again. Extension springs absorb and store energy as well as create a resistance to a pulling force. 
Applications: Applications for extension springs include automotive interiors and exteriors, garage door assemblies, vise-grip pliers, carburetors, trampolines, washing devices, farm machinery, toys as well as thousands of other uses. Extension springs come in a wide array of sizes, from small medical devices to off-road machinery brake springs.
