calimaero® HWG 150mm Air Vent Covers for Walls 6 inch Cowled External Extractor Fan Vent Cover with Backdraft Shutter, Stainless Steel, Robust, Weatherproof Fits only with Metal Ducts

Well made and solid. Looks good in place of the original plastic louvred cowl.internal flap rubber edged for quiet closure. Can recommend.

Far better than the previous plastic one I had. Thus us for a 6inch diameter hole. It’s good quality and looks superior to the run of the mill plastic ones

First impression was a quality built item, however, when came to fitting the cover, the base gasket did not fit ! (about 10mm short each side). Very frustrating .... get 3 sides on then always came off when trying to fit the 4th side. Yes, tried warming in hot water and stretching .... ended up splitting one of corners ....but at least I can now get the gasket to stay on ! I’ve now had to complete to gasket/seal with some black silicone (at extra expense !). This was an expensive solution (thinking it was going to be the ‘bees knees’ ..... Maybe I should have gone for the cheaper option from ‘Spares2Go’ at £18.89.... looks exactly the same product from photos !!

Excellent well built product but with a major flawThe non return flap needs to either have a magnetic catch or a spring fittedI've only just fitted mine 24 hours ago and the constant clinking of the flap is driving us crazyEven in the very lighted breezeMaybe it's our locationHave ordered the in line no return unit to see if this will helpWill update my review
