I have a 10 by 6 foot greenhouse with two roof vents. It came with manual vent levers. I replaced one with an automatic vent opener, a heavy dury Ellovent, which can be disabled in seconds by unhooking one end. However, when the vent is closed the opener takes up a lot of room, getting in the way. Otherwise it looks very good. Are there any other automatic vent openers that can be disabled easily, without removing it from the frame, which take up less room? I will replace the other manual opener with an automatic one.

I’ve added a photo of the installed vent closer.
