Rion greenhouse roof vent in used, working condition with all original components and manual. Can be opened manually or you can use a wax cylinder to operate automatically through interior greenhouse temperature. Will do the trick for venting a small Rion greenhouse. Better price than $169 at the big box store for a new one.

Some shade compound and sheathing tape remaining on the frame. Used as a makeshift roof vent on my high tunnel greenhouse for 2 years.

Located in Carstairs but can meet in Airdrie for drop off.
