This Lofrans 6mm Anchor Chain is a high-performance, calibrated marine chain engineered for reliability in the harshest seafaring conditions. Manufactured from Grade 40 (G40) steel, it offers significantly higher tensile strength—approximately 30-50% more than standard Grade 30 chain—providing peace of mind when anchoring in heavy weather or strong currents.
Finished with a heavy-duty hot-dip galvanisation, this chain provides superior corrosion resistance against saltwater. For authenticity, each section features the "LFR" mark engraved every 30cm, signifying a genuine Lofrans product.

Questions & Answers
Is this a genuine original part?
Yes, this is a genuine Lofrans product, featuring the "LFR" authenticity hallmark on the links.
How do I know if it is compatible?
We recommend checking your windlass gypsy for an "ISO 4565" or "6mm" stamp. If your current setup uses 6mm calibrated chain, this G40 version is a direct upgrade.
What is the difference between Grade 30 and Grade 40?
Grade 40 (G40) is a "High Test" carbon steel chain. It provides a higher strength-to-weight ratio than standard Grade 30, allowing for a 2,400kg breaking load in a compact 6mm size.
Note: Please verify your windlass gypsy dimensions (Pitch/Diameter) against the technical specs above before purchasing. Sold per meter unless otherwise stated.
