Does anyone know if there is a "louvre" end cover that I can buy on

Yes, various options in the sheds. However most anti back draft shutters
are gravity operated and rely on the vent being vertical. If your outlet
is horizontal they won't work as is. You'll need to find something that
can go in line somewhere or prehaps adapt a vent with a anti back draft
plate to work in line.

ISTR that the Marley site is pretty good for showing what they make.
