Premium heat tempered s curve extension spring
✔️ 2mm steel wire gauge 22mm coil width 180mm length

Sized for individual fitments, this heavy duty tension coil delivers consistent recovery force for rigging projects that demand reliability over slack. Mechanics and builders mount them in trailer straps, shop lifts, and marine tackle systems where steady pull prevents shifting during transit.

✅ Free length measures exactly 180 millimeters from tip to tip
✅ Outer coil diameter holds steady at twenty two millimeters
✅ Core wire thickness sits at two millimeters to handle high loads

💡What is the best method to preload heavy duty dual hook tension springs on marine and workshop fixtures without risking structural fatigue? A handy installation relies on precise spacing and smooth friction paths to lock in tension safely. - Verify the unstretched travel gap between your anchor studs before bolting any hardware. - Thread a manual winch crane through the loop eyes to apply controlled pull evenly. - Grease the internal hook curves with waterproof synthetic spray to eliminate metal on metal drag. - Maintain all routing angles above five times the wire gauge thickness to avoid permanent coil wear.
