Cross Reference Guides

This cross reference guide offers the best cross reference from other drain manufacturer’s products to a Josam equivalent series. You may need to add options to the Josam series to match the other manufacturer’s options. In some cases, adding options on a competitor’s model will require a different Josam series than the one selected in this chart. If you need assistance with product cross reference, please contact  Josam Customer Service.
