ISO Proof Coil Chain ― General Purpose/Anchor Chain ― G30

ISO proof coil chain is a standard-duty galvanized chain for applications where proof coil chain is the correct specification. It may be used in general marine or anchor-related applications only when the size, grade, and use case are properly matched. Choose this chain when the application calls for standard-duty galvanized chain and does not require a high-test chain upgrade. If you are building or replacing an anchor rode, confirm whether proof coil, high-test, or calibrated windlass chain is the right choice for your boat and windlass. Best for: Dealers, yards, distributors, and buyers who need standard-duty galvanized chain by specification. Check before ordering: Confirm the chain standard, grade, application, and whether windlass compatibility is required.
