ABSTRACT:
One aspect of the invention provides a vent which comprises a body member and an adjustment member. The body member comprises a vent passageway that extends from an inward side to an outward side of the body member. The body member also comprises a collar having a collar passageway that extends from an inward side to an outward side of the collar. The collar passageway is in fluid communication with the vent passageway. The adjustment member comprises a head disposed to adjustably restrict a flow of air through the vent passageway and an inwardly projecting stem having one or more stem portions. The one or more stem portions comprise one or more contact portions which engage an interior surface of the collar and which adjustably couple the adjustment member to the body member. The one or more stem portions, alone or in combination with the interior surface of the collar, define one or more collar openings that extend through the collar passageway. Air flowing through the vent may flow through the collar openings.
