Hello,
and first of all, sorry for the late reply. We are chaotic and happy, having moved by now, and only got internet again yesterday :). The fact that the rail no longer exists is exactly my problem too, which is why I don't yet know whether I will use the system for the new kitchen again. I do have rails, but they were cut to the dimensions of the old kitchen and I don't know if they can be used again here. If not, I'll get back to you and give you the measurements; if you want, I can send them to you – of course, without payment. But it might take a little while; the carpenter building the kitchen has few available appointments :(.
Best regards
