ᐅ RATIONELL N full-extension drawer slide with soft-close mechanism

Hello,
I still have a problem that I couldn’t find any information on.
Maybe someone here can help me once again.

I have full-extension RATIONELL N drawer slides on all my kitchen drawers. Is it possible to add soft-closing to these? I can only find information about RATIONELL B or H.

Hello, what is N supposed to be?
The labels RATIONELL B, H, I were only used in the German Faktum follow-up purchase.

Hello,
yes, I was wondering about that too. That is what is shown on my invoice.
Here are the item numbers for the drawers:

201.070.76
101.070.86
600.359.16
901.070.73

I think I have found it now. It is probably RATIONELL B.

Yes, they are from Blum. In 2006, dampers for the drawers were introduced. It is possible that an N was added at that time to indicate the new version.
