The Door Extension Kit allows raising your Riga 2s, 3s, or 4s by 20″ to fill the area above the door when the greenhouse is installed on a raised foundation. You have to place your greenhouse kit on a stem wall. This reduces the need to construct a style to get over a raised door frame. With the door extension, you will get more headroom at the entrance.
