TENSION SPRINGS - These tension springs feature drawstrings, tension belts, carabineers, and eyelets for easy attachment. The design ensures even stress distribution across the spring, improving texture and durability. Resistant to breaking, these springs are widely used in marine, computer, electronics, automotive, mold, biological, chemical, aerospace, railway, nuclear, wind, and thermal power industries. DOUBLE HOOK DESIGN - The dual hook tension spring features a double hook configuration for quick attachment to lanyards, tension bands, carabineers, and other fixtures. Sealed safety holes prevent fasteners from disengaging, making them suitable for extended outdoor use. High-quality construction provides strength, durability, and long service life. Resistant to rust. Manufactured under strict quality control with multiple forging processes for reliable performance. DURABLE CONSTRUCTION - No tools required for installation. Simply connect the ends as needed. Designed with high tensile strength and consistent, stable force. End hooks are robust and long-lasting. Made from spring steel with a nickel-plated finish to enhance durability and wear resistance. WEAR-RESISTANT MATERIAL - Constructed from stainless steel for superior durability and corrosion resistance. Suitable for applications in manufacturing, assembly, research and development, and maintenance. Resists wear, extreme temperatures, and corrosion. Smooth surface finish achieved through polishing for improved performance. WIDE APPLICATION - Ideal for use as a garage attachment for awnings, punching bags, hammocks, and similar items. Commonly used in production, assembly, R&D, maintenance, and various projects involving gates, screens, and industrial equipment. Wire diameter approximately 3 mm.
