just finished hanging a window wall for a restaurant. 7-9'0'' X 3' 0" store front glass doors. Six of them are connected and fold back together for outside patio seating when the weather is nice. One is individually hung for out door access when the others are not folded back. It is a Hafele system but Nana wall is similar. Interesting challenge for a wood worker, no hill for someone anal.
Decipher directions, execute,..... fortunately the hardware and I think the insstsructions came from Australia so I had a fighting chance! Other than the mm conversion
