Lofrans Calibrated Anchor Chain is the gold standard for marine anchoring systems. Unlike standard hardware store chain, this marine-grade chain is Grade 40 (G40), offering approximately 30% higher breaking strength than standard Grade 30 alternatives. Each length is precision-calibrated to ensure seamless operation with your boat's windlass gypsy, preventing jumping or jamming during critical anchoring maneuvers.
Key Features
- ✔ Grade 40 Steel: High tensile strength for heavy-duty marine use.
- ✔ Hot Dip Galvanized: Superior corrosion resistance vs. zinc plating.
- ✔ Precision Calibrated: Exact dimensions for windlass compatibility.
- ✔ Italian Made: Produced by Lofrans under strict quality control.

Questions & Answers
Is this a genuine original part?
Yes, this is genuine Lofrans calibrated anchor chain. It is manufactured in Italy and features the "LFR" authenticity mark engraved on the links every 30cm.
How do I know if I need ISO or DIN 10mm chain?
The critical difference is the pitch (internal length). ISO 4565 has a 30mm pitch, while DIN 766 has a 28mm pitch. You should check the stamp on your windlass gypsy; it will typically indicate "10 ISO" or "10 DIN." Using the wrong standard will cause the chain to bind or jump under load.
What makes Grade 40 (G40) better than Grade 30?
Grade 40 steel has a higher carbon content and undergoes specialized heat treatment, resulting in a breaking strength roughly 30% higher than standard G30/L-grade chain of the same diameter. This allows for increased safety margins or the use of a smaller, lighter chain for the same strength requirement.
Note: Please verify your windlass gypsy calibration (ISO vs DIN) before purchasing. For lengths over 25m, please contact 4boats.co.uk for specialized shipping quotes.
