I was just looking at stud wall pattress boxes. I have used double boards for my wall construction, so need 22.5mm depth.

Norslo DL147N have 30mm depth

 

I thought I’d post this for anybody looking for this in the future. 

Wish I’d seen this before as I tried to hack out the OSB behind the plasterboard to get the lugs to fit. 🤦‍♂️

How many of the Loxone back boxes do you need? I have some spare I could send you. 

I honestly can’t remember at the moment. I see that they’re also used for the occupancy sensors so need to look into whether I need them for that. I’ll get back to you and thank you!

But not the surface mount type. Ask me how I know 😂

Snip the little tabs off that I’ve marked red and problem solved. They just stop the wings/lugs pushing back like some of the cheaper dry liners do. Usually ok without though. 
 

Next time fit them before skim coat or do it properly with nogs and metals boxes!! That way you don’t get the lip of the box showing either

Re the Norslo boxes - good find.
