Description: Negative pressure air vent for the ventilation of rolled or shingled felt roof structures. Installed in a chain on the ridge of a roof using SNAP couplings. The design of the product prevents water and snow from entering the building structures. If the product is to be installed in an area where hard winds and snow storms are common, we recommended the Alipai Ridge instead of this product.
