Product is as described and looks clean and tidy in situ. Most important it works as required and expected. ### ⭐⭐⭐⭐⭐ Good and efficient construction which works well *by A***R on 26 February 2025* Good and strong construction, works well, price is right ### ⭐⭐⭐⭐ Great, but needs adjustment *by J***D on 23 August 2014* I have moved into a new house and the bathroom fan has a 6" outlet with no cover, so the wind whistles through and makes the bathroom very cold (perfect for a room where you are guaranteed to be both naked and wet at the same time!). Bought one of these to stop the wind getting in. Perhaps my fan is a slightly different size or I should have bought something to connect the two pipes together, but unfortunately this grille is slightly too big for the fan pipe and blows off when the fan is turned on (quite comical to watch). Fortunately I bought some one inch Gorilla Tape , wrapped it around the outside of the fan pipe about four times and put this grille on creating a very tight fit. Came wrapped in a thin sheet of bubble wrap and a black plastic bag, wrapped with tape. Fortunately not destroyed by the Royal Mail monkeys at the sorting office. I now have a warm bathroom and am very happy. ## Frequently Bought Together - Blauberg Black Gravity Grille 150mm - 7.25 inch External Ducting Air Vent with Round Spigot and Non-Return Shutters for HVAC Bathroom Extractor Fan Kitchen Whole House Ventilation Grill Cover - Kair Plastic Ducting Pipe 150mm - 6 inch / 350mm Short Length -Rigid Straight Duct Channel - 150mm Pack of 2 Adjustable 140-160mm Stainless Steel Pipe Clamp Secure Hose Clip Inline Duct Extractor Fan Cooker Hood --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/51663175-blauberg-100mm-4-inch-black-gravity-shutter-vent-grille-155x155mm](https://www.desertcart.co.th/products/51663175-blauberg-100mm-4-inch-black-gravity-shutter-vent-grille-155x155mm) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-29*
