The Lofrans' 72750 is a professional-grade 6mm anchor chain engineered specifically for marine windlass applications.

Questions & Answers
Is this a genuine original part?
Yes, this is a genuine Lofrans' product, manufactured in Italy and engraved with the LFR authenticity mark.
What is the difference between ISO 4565 and DIN 766 for 6mm chain?
For 6mm diameter chain, the dimensions for ISO 4565 and DIN 766 are identical (18mm pitch), meaning this chain is compatible with gypsies designed for either standard.
Is G40 chain safe for my windlass?
Absolutely. G40 refers to the strength of the steel (Grade 40). As long as the diameter and pitch (6mm / 18mm) match your windlass gypsy, G40 provides a higher safety factor than standard G30 chain.
Note: Chain is a heavy item. Please ensure your anchor locker and windlass are rated for 6mm calibrated chain before installation. Refer to your manufacturer manual at 4boats.co.uk for specific windlass settings.
