Claim:
A vent assembly for controlling the flow of air through an opening, comprising: a wooden vent cover comprising a plurality of fixed position wooden vanes each having respective first and second major surfaces with at least a plurality of air flow openings defined in part by a first major surface of one vane and a second major surface of an adjacent vane, the first and second major surfaces being from about twelve degrees to about seventeen degrees of vertical when the wooden vent cover is in a horizontal orientation; an air flow regulator slidable relative to the wooden vent cover from a first closed position in which the air flow regulator substantially blocks the flow of air through the air flow openings to second open positions in which air flow paths are provided through the air flow regulator and the air flow openings; and couplers operable to slidably couple the air flow regulator to the wooden vent cover, each of said couplers comprising a body having a first support portion positioned to support the air flow regulator and a second wooden vent cover engagement portion in frictional engagement with the wooden vent cover.
