People,

where can I find a lower cost wall vent cap cover? low profile mount
onto stucco.

wal cap 8 inch diameter louvered type
found $270 at Copperlabs [aka Vents USA] in MN
and $180 at Thunderbird in CA

I'm convinced that it would be best to have louvered in addition to
the damper inside at the stove top hood.

But these prices seem a bit high for a metal box, some 'flippy' vanes,
and a short 8 inch diameter tube.

Anyone know of another outlet? with lower prices?

Try this place: http://www.famcomfg.com/wall-vents.html

They have a plastic one for 12 bucks, and a variety of metal types for
under 50.

HTH,

Paul F.
