ISO High Test Chain uses carbon steel with a higher tensile strength than proof coil chain – providing a greater strength-to-weight ratio.
This is a short link chain, which makes it less likely to kink, and is ideally suited as a windlass chain.

Note that this “short link” G43 chain is made to ISO specifications, and has shorter links than NACM G43 chain – refer to the specification table for all the relevant specifications. Check fit or contact windlass manufacturer before purchase.
For easy identification, the grade type “G43” and the logo “CMP” is embossed every 12 links.
