If anyone has a Darche Elcipse 4wd awning I wonder if you could do me a favour & measure the size of the sailtrack?

I'm thinking of buying one & using cheaper/lighter Kings awning sides with it - they have 7mm sailtrack cord (Keder) on them.

Wrote to Darche almost 3 weeks ago, got an automated response saying they would get back to me within one business day, but have heard nothing.
