Black Gravity Grille 155mm External Dimension with 100mm - 4 inch Round Rear Spigot and Not-Return Shutters Ducting Air Vent

Extractor grille arrived on time in excellent condition. The rear of the grille has stepped connection to accommodate three different size pipes/hoses. The grille looks well when fitted and works perfectly.

Our original white vent cover discoloured and broke because of age so I needed a replacement. This time we chose black. For me it looked more sturdy than the white version and shouldn’t discolour like the white version. These seem to be a standard size so there was no need to re-drill walls in our external wall making it so much easier to install. It works well and does the job. Very pleased and recommended.

Overview: Well made, durable ventilation cover.Disclaimer: I don’t know what I’m doing, I really don’t! This is the first ventilation cover I’ve installed. Hopefully if you don’t know what you’re doing either, then this review helps! I also bought this after the initial purchase I made was too big. A reminder to check the sizing - 100mm is the diameter of the insert that goes into the wall.Postage and Packaging: Nice and quick, but the packaging within the amazon box was a polythene bag. This is quickly becoming the norm where there is no commercial packaging included at all.First Impressions: The vent cover is a matt black and as such is not jet black to the eye. Its not grey, but certainly with the lack of shine it displays, then it is certainly not Jet black either. Other than that it seems well made and an appropriate standard. There is nothing else included in the package - no screws or Raul plugs. This isn’t an issue if you are replacing a current vent cover, and not much of an issue with a new install.Design: I’ve already covered the matt nature - and this is down to it being slight textured to the touch. Other than that, it has 3 horizontal slats, as opposed to the 4 that my previous one had. I suspect that the 3 will be slightly more resistant to airflow which may help in wind but other than that I don’t know what relevance it has.Figment and use: The screw holes for my old one were not quite in the same place, so new holes needed to be drilled and new rawl plugs used. Other than that, the holes on the cover allow a little latitude to move it for a precise fitting. Once installed, it pretty much stays there. The biggest negative I’ve read in previous reviews is that the slats move in the wind creating a clacking/banging noise. Its early days, and I suspect it is very dependant on individual houses. If this happens and it is enough to want to go to the effort to solve, I suspect sticking a small gel nub on the back of slats would stop it fine.Longevity: Its a cover. The previous one lasted for a good 14 years since the house was built. I suspect that this should last longer with no issues. However, if it does fail in a short period then as always I will update this review

Great! Does the job!

The spigot fitted like a glove - a perfect replacement for the original vent.

maybe this just got twisted while in storage but it is a bit warped, other than that its OK

Good quality great price comparing with local builders merchants 70percent cheaper

It turned up on time. It fits the hole. Birds no longer try to nest in my extractor fan. My life is now full of joy and happiness, due to this flappy plastic cover.
