Each anchor, anchor rode, and windlass needs a specific chain model to work with, but identifying which one you need can be quite confusing... we get that. Many available in the market have similar names, so knowing how to differentiate them can be the key to avoiding any mistakes. That's why MAURIPRO has created the following Chain Dimensions Guide (or table) to help you find the model you need!

If you are unsure which chain model you currently have or aren't sure which chain will fit your unit, measure it as shown on the diagram on the left and match it to the D, P & W measurements to find out!
