Abstract
An exhaust vent including a roof cap inlet and a roof cap outlet which are joined together without the use of fasteners and which defines a vent for use in venting gases from the inside of a building structure. The roof cap inlet includes a base portion defining an aperture and including a cylindrical extension extending below the base portion for attachment to a duct, and a rectangular extension extending above the base portion for preventing ingestion of water through the aperture. The roof cap outlet is formed with a semicircular portion defining a flow passage and includes a hemispherical portion defining a closed end for the flow passage wherein the design of the roof cap outlet provides increased strength against deformation, and the hemispherical and semicircular shape of the roof cap outlet facilitates flow of gases through the exhaust vent to the outlet opening.
