Monticello Greenhouse 18" Louver Wall Mounted Window with solar powered opener

The RSI louvered window vent helps to cool the inside temperatures of any greenhouse or structure. With its simple but proven design, the louver window, made from extruded aluminum, automatically opens and closes based on the interior temperature of the structure. This vent is easy to install and will require tools to cut the needed opening into the structure wall. The lover size is approx. 18” x 18” squared and when closed the louver slats overlap each other preventing insects and animals from entering.
