Abstract
An exterior ventilation device having a main body with an upstanding perimeter wall and an attachment flange extending outwardly from the upstanding perimeter wall. A plurality of louvers extend across the body adjacent to the other end of the perimeter wall each of the louvers being sloped downwardly and outwardly. A trim ring is attachable to the main body and defines a cavity between the attachment flange and the skirt of the trim ring into which siding may be inserted. The body is provided with a water directing rib to direct any water running down the body from the back of the body towards the front of the body and thus outside of any cladding material located in the cavity between the trim ring and the attachment flange. In one embodiment the water directing feature is a rib and in another embodiment the feature is a groove. In a further embodiment the body includes sloped portions of the perimeter wall and the water directing feature begins spaced apart from the attachment flange and not directly adjacent it.
