304 Stainless Steel Double Loop Extension Spring
Manufactured from 304 stainless steel for superior corrosion resistance, delivering stable axial tension via double round-loop ends for precision and outdoor applications with high anti-corrosion requirements.
Precision cold-wound from SUS304 high-quality stainless steel wire with a stable built-in initial tension for immediate gap elimination at the start of extension. The large round loop ends are precision-formed for high strength and a smooth surface that protects mating hardware. No plating required — the stainless steel body inherently resists acid mist, saltwater, and humid environments. Available in large and small sizes within the same series to fit different installation spaces and load requirements.
