Manrose Square Flap Vent Brown 100mm is rated 4.4 out of 5 by 9.
Rated 5 out of 5 by from Nice Design This flap is a nice design that is allows the fitment of 100mm round or rectangle ducting; by simply snapping off some plates when required for round. Fitted two of these externally no problems for kitchen and bathroom extractors. The flaps so far are doing their job well. I did hear a bit of chattering the other day in some strong winds; but they are at least still present unlike so many you see; this will only tell in time I guess.

Rated 4 out of 5 by from Good Flap Vent Does the job and easy to install. So you can't go wrong.

Rated 4 out of 5 by from Does the job but needs sealant I wish I had known that it can be modified by breaking off tabs to use rectangular ducting, I had bought and installed an adaptor and a length of round ducting. The outlet only locates on the ducting using some tabs rather than a proper flange so there is a need for silicon sealant to ensure all the exhaust air goes where it should do.
