Questions & Answers
Is this a genuine original part?
Yes, this is a genuine Lofrans product. It features the "LFR" marking every 30cm.
How do I know if I need ISO or DIN chain?
While both look similar, the link dimensions (pitch) differ. Always check the marking on your windlass gypsy; it will specify "12mm ISO" or the DIN equivalent.
What are the benefits of Grade 40 (G40) over Grade 30?
G40 chain has approximately 30% higher breaking strength than standard Grade 30 chain. This allows you to use a lighter or smaller chain for the same holding power, or provides a much higher safety margin for your vessel.
Note: Please verify your windlass gypsy compatibility against the ISO 4565 standard before purchase. Distributed by 4boats.co.uk.
