The chain feeding through your windlass gypsy needs to perform link by link, without slipping, jamming, or skipping - and that only happens when every link in the chain has been manufactured to exactly the same dimensions. That's precisely what calibrated chain delivers.\u003c\/p\u003e\n\u003cp\u003eUnlike standard welded chain, calibrated anchor chain is produced to tight dimensional tolerances, ensuring a consistent pitch - the internal distance between links - throughout the entire length. A windlass doesn't simply haul chain; it engages each link individually through a notched sprocket wheel. Feed it chain that isn't built to that sprocket's exact specification, and the system will tell you immediately, usually at the least convenient moment.\u003c\/p\u003e\n\u003cp\u003eOur calibrated windlass chains are manufactured to DIN 766 and ISO 4565 (also known as EN 24565 and BS 7160) - the two internationally recognised standards specified by the majority of windlass manufacturers including Maxwell, Lofrans, Quick, and Lewmar. Available in sizes from 6mm to 16mm, there's an option to suit virtually every windlass on the market. When ordering, always check your windlass manufacturer's documentation to confirm the chain size and standard required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTwo Options to Suit Every Application\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFor saltwater and tidal environments where appearance and longevity matter in equal measure, our Grade 316 stainless steel calibrated chain offers outstanding corrosion resistance and a clean finish that holds up to prolonged submersion.\u003c\/p\u003e\n\u003cp\u003eFor those seeking proven heavy-duty performance, our zinc-plated galvanised calibrated chain has been the workhorse of marine anchoring for generations.
