Looking for 2 flow frames (Switzerland)

Hi all
I’d like to modify my classic cedar 6 frame super to fit on a standard 10-frame Dadant brood box. To do that I’m looking for 2 flow frames to fill the missing width space in the super due to the larger 10-frame Dadant brood box beneath it.

So far I’ve modified the original Langstrooth 8-frame brood box to accomodate 8 Dadant brood frames and on top of it I add the 6 super/flow frames, but I’m not satisfied with the result because the actual brood box configuration with bees on 8 frames feels too “tight” for the bees.
I’m based in Switzerland.

Cheerio, Micko
