Calibrated Chain - Stainless Steel

When you purchase a calibrated chain, it’s important to know what chain suits your windlass for the best fit. The majority of windlasses require chain in accordance with either DIN 766 or ISO 4565.

A combination of wire diameter, link outside width and most importantly the chain pitch (inside link length) must be consistent throughout the length of the chain to ensure the best fit in the gypsy.


To produce a calibrated chain the manufacturer would normally weld the chain shorter than required. It would then be subjected to a further process of calibration. This process pulls each link to a constant length within a tolerance.


Our calibrated chain is supplied with a certificate of conformity and test. This confirms that the chain has been subjected to a proof load and our in-house batch testing ensures that the chain can withstand the minimum breaking load.
