ABSTRACT:
A ventilating device covers an opening in a structure and includes longitudinally-extending compartments, each of the compartments having longitudinally-extending side walls. A baffle is placed in the compartments, and is otherwise unattached to the ventilating device. The baffle is movable from an inactive position permitting communication through the ventilating device to an active position closing off communication to thereby prevent wind-driven moisture from being driven into the ventilating device.
