Review: Perfect fit and easy to install - Fits perfectly and was very easy to install. The build quality feels good and it does the job well. The flyscreen is a nice added feature too. Only downside is that it doesn’t come with screws, so you’ll need to have your own ready. Overall, a good product and does exactly what it’s meant to do. Review: Good product, bit of effort to get it to fit. - Received day after ordering as expected. I noted that this item gets returned often due to being the wrong size, I must admit I thought I was going to have to return it as it was too big for the pipe in the wall, but then realised that if I squeezed the bit that goes into the wall pipe, it was a struggle, but it fitted. It's fitted so tightly I don't think I'm going to have to glue it to the wall. (I don't 'do drills'). ## Features - White plastic ducting air outlet / inlet square grille with fixed louvres and anti insect mesh / flyscreen. - 155mm x 155mm external dimension with 4 inch / 100mm round male rear spigot on the back of the grille can be cut off if flat surface preferred. - Louvre can be flicked open with flat head screwdriver for ease of installation and to allow cleaning of insect screen. - Fits inside Kair 100mm round female duct Pipe Part: DUCVKC250 or 102mm flexible hose Part: DUCP0092/102/35. - Easy to install, just push-fit duct and fittings together.

I can't say for sure a mouse couldn't get in, but it would have to do some major chewing work to do so. We got this to sort a wasp problem and it worked a treat. **Q: Does this vent come with screw fixings?** A: No fixings were supplied with mine. Just a tip to remove the outer grille you need to use a flat knife push down on one of the edges and lever it off.when fixing the back plate don't over tighten screws or the grille will be hard to press on. **Q: Can I buy a plastic ducting connector that will fit into the 150mm grill?** A: Yes, buy plastic zip ties and use one of them **Q: What is the size of the 'clicked in place' removable grille, and could this part be supplied seperately.** A: The grille is the size of the square vent and you will have to ask the supplier if the sell it separately. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect fit and easy to install *by M***I on 25 April 2026* Fits perfectly and was very easy to install.
