External Vents
A sloped roof vent has a coated steel plate with a raised center and a gasket receiver is formed around a central hole. A structural body is crimped with a gasket in the receiver. The body has an outer wall extending downward over the receiver. A sloping wall extends inward and a vertical wall supports a second sloping wall with an inner rim. A damper staked to an axle covers the rim. Inserts keep the damper from chattering and fully closing. Wind walls prevent outer drafts from lifting the damper. Two fasteners attach caps to the outer wall. Lanced and pressed ledges on a push-in hose connector permanently engage windows on the inner rim of the structural body. A snap-in screen and a hose connector reducer complete a package.
