The side panels with windows are actually Accessories for 3M Pavilion. I bought it, 2 piece striped in blue and white, and thus complete the protection of my blue-white-striped Doppelarmmarkise 3x3m by a very affordable wind and rain protection. Now no longer bothers Weather My relaxation on the garden terrace .... Unfortunately, the velcro strips are sewn rather quickly when the wind has ruffled violently, but with a few pinpricks they are also re-tuned. For the price - always happy !! Thank you!
