Rocker arm spring, progressive / stainless steel

With a spring mooring line, you will never have another rough night at sea. The spring works progressively, with the tighter coils activating first, followed by the wider coils. The spring operates smoothly and without jerks. The elastic limit is not exceeded, and there is no risk of breakage. The spring retains its mechanical properties.
Stainless steel spring mooring lines ensure that the shocks from your boat's mooring lines are absorbed.
