Reducing cable link

Does anybody know whether Digikey has something similar to this product: LINK CU REDUCING LINK 50MM-16MM | Lugs and Links | Installation | All Categories | CNW
I cannot find anything similar which I could buy in Germany.

I need to connect two cables. One cables has the cross-section of 50 mm^2, the second one has the cross-section of 16 mm^2 (it can also be 10 mm^2). Any alternative solutions are welcome. Thank you.

Greetings,

Would something such as the SR-0-XY work for you? It appears that your wire sizes would correlate roughly to a 0 and 7 AWG, which is within the range that this product should accommodate.

Greetings,

Yes, it should work! Thank you for the help.
