## Questions & Answers

**Q: Is the maximum length between the front of the plasterboard to the block work still 40 mm with that version or is it longer?**
A: Hi Marc! Yes, across the whole Corefix range the maximum length from the face of the plasterboard to the block work is 40mm. The difference of size between Corefix Plus 30, Original and Air is the length of the screw supplied with Plus 30, allowing for a 30mm deep bracket/batten to be fixed to the face of the plasterboard. We are an innovations business so watch this space as the Corefix range grows to cover greater than 40mm.

**Q: I have a very large heavy mirror with 2 hooks either side would these be suitable to hang it off and on just a masonry wall? thanks**
A: Hi there, thank you for your interest in Corefix. I can confirm the as long as the safe working loads and installation instructions are followed then Corefix will work well for your needs. Hope this helps you make an informed decision. Many thanks from the team at Metex

**Q: Can these be used to hang a 16kg cooker hood?**
A: Yes. I can hang off mine (I used 4 to connect a hook to an external wall)

**Q: What diameter raw plug is it?**
A: You need a 10mm bit to get the rawl plug in the wall

### ⭐⭐⭐⭐ Good fixing
*by D***D on 4 February 2020*

I've just used 3 of these to attach an old (fairly weighty) 32 inch TV on a cantilever bracket to a 25mm insulated dot and dab wall. I reckon I'm spanning at least a 40mm gap not including the 12.5mm plasterboard. I'm a little apprehensive whether or not they will hold for any length of time as it does say on the packet they they aren't ideal for cantilever loads for obvious reasons. As I'm spanning such a large gap, I unfortunately missed the hole in the bricks and the first plug snapped fairly easily, which was a little concerning but the other 3 I was more careful with and they went in with no issues. I can't really see why if there is approx 40/45mm of plastic plug in the wall, and the screw is expanding the plug into the brick work correctly why these won't hold efficiently. I guess time will tell, I'll just make sure not to sit underneath it for too long.
