ISO4565 Windlass Chain ― G30

ISO4565 G30 windlass chain is a standard-duty galvanized chain for compatible ISO metric windlass systems. It may be used where the windlass and anchoring setup specifically require ISO4565 chain dimensions. Choose this chain only when ISO4565 is the confirmed chain standard for the windlass. Do not choose chain by diameter alone, because different metric standards may not feed correctly through the same gypsy. Best for: Replacement chain on compatible ISO4565 windlass systems. Check before ordering: Confirm windlass gypsy, chain standard, and product availability.
