Extension Spring #70

The 18570 Extension Spring #70 is a durable tension spring designed to provide reliable pulling force and return action in mechanical assemblies and equipment. Manufactured from high-quality spring steel, it delivers consistent elasticity and dependable performance for repair, replacement, and general mechanical applications. Its long, narrow design allows it to stretch under load and return components to their original position—because a good spring always knows how to snap back into action.
