Double Cardan allows the stainless steel spring to always work with perfect axiality and parallelism, independently of the traction angle created by the boat movements, the ESSENTIAL factor against torsion spring fatigue (as can be seen from the twisting of chains) which leads to premature rupture of the spring. Double Cardan is already equipped with adequate shackles for perfect installation.
