Rated 4 out of 5 by from Not bad for the money The flaps have a tendency to stick if the body is not fitted 100% dead straight however, this can be overcome by deburring the edges with some fine sandpaper. The body plastic can be brittle and will crack if overtightened

Rated 5 out of 5 by from Square Flap Vent Does exactly what it's supposed to do. Great price and service from Screwfix. Whole job, including travelling to and from Screwfix, to fitted and operating took less than an hour.

Rated 4 out of 5 by from Manrose flap As described. Bit smaller than the one it was replacing, so check size first. Be interesting to see how it stands up the light being brown. Hopefully better than the previous (unknown source) white one which was very brittle and disintegrating after about 5 years. Pity there is no black one, as my gutters and downpipes are all black

Rated 5 out of 5 by from Excellent product I used this item as the external cover for a tumble drier vent (using rectangular duct but it fits both rectangular and circular ducting) - works perfectly. Four hidden screw holes allow fixing to the wall so it fits tight and secure to the wall. Well made and good quality - very pleased.
