Review: Reliable vent grille I regularly use for client installations - Pros: Good quality plastic with a clean white finish — looks professional once installed Integrated flyscreen helps prevent bugs and debris Fast delivery every time I’ve ordered — reliable for project timelines Fits standard 150mm ducting perfectly Cons: None so far — has always arrived in good condition and does the job I’ll continue buying this for future projects. It’s dependable, easy to work with, and arrives quickly — all important when managing client work.
Review: Decent grill. - Good vent with mesh to keep out unwanted pests!! Lugs quite sturdy when removing grill to enable you to screw it to wall. As others have said, make sure you put it on the right way otherwise the lugs don't line up! Would definitely buy again.

## Questions & Answers

**Q: Does the mesh protect against mice?**
A: The louvered slat gaps are very narrow and then there is a plastic mesh that then sits within it. 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.

### ⭐⭐⭐⭐ Slight issue
*by D***N on 1 May 2025*

I had problems reinserting the insect mesh after screwing vent to the wall because inserting the grill caused the louvre to bow a little. Apart from that it was easy to fit and was the right size.
