Ours looks very much like this. The AL salesman said it was just the same as the Protec.
What I'm interested in here, though - and maybe I should start a new thread for the question - is is it correct to close the top while the canvas "bellows" is wet? I've dried it out following the clean-up prior to covering, so I'm fairly confident I've done the best I can. But what if I need to close it while still wet, following rainfall, in readiness for moving to another site, or, if the weather is really bad, for going home?
