We’ve run into some confusion with the Murrplastik line of drag chain accessories. I’ll do my best to summarize the info I found below for how these are organized.
First off the document that’s most relevant here is the following Murrplastik catalog: https://assets.indi.nl/pdf/nl_NL/overview_mp3000.pdf
The chain body in particular is interesting. It looks like the part number should be 0300-02-062-xxx-0-0-yyyy with “xxx” being the bend radius and “yyyy” being the total length in milllimeters. However, we don’t carry the lengths of drag chain in that width. Looking at what’s actually available it seems that there is another version of this numbering system, which gives us options for the individual chain links seen in the following results: https://www.digikey.com/en/products/filter/industrial-automation-accessories/800?s=N4IgTCBcDaIAwGY7IGxgAQgLoF8g
