Side vents increase the effectiveness of roof vents by allowing winds to enter from a low area and push hot air out of the roof vents. All side vents are made of aluminum painted to match the greenhouse and come with panels that match the greenhouse covering if ordered at the same time. It is recommended that side vents be purchased in pairs placing one vent on each side of the greenhouse. Standard side vent placement is 6" above the greenhouse base. They are automated with the same Bayliss triple spring vent opener used with the roof vents (included). Dimensions: 24" wide x 48" long
*Must be ordered with a Cross Country greenhouse.
