I have a cooktop exhaust vent that is routed to the outside of the

Unfortunately the flat on the vent never closes - letting cold air in

Where do I find a replacement vent( I didn't see it at the home deopt)?

FWIW, our Broan range vent has flappers on the onside over the stove
and on the outside wall outlet. The outside flap assembly was in stock
at Lowes where we bought it. A little hard for the clerk to find,
until we gave him the part number from the installation instructions.
