Quick backstory: had a room replastered, guys brought an "electrician" who was told that there would be a small patch panel fitted to the wall, and to leave a channel for the incoming cat6 cables so I can do my thing once they were done.
What I got was a pair of metal 2-gang back boxes wedged in and "held in place" with decorators caulk, and a matching letterbox in my nice new plaster.
I decided to just put a couple of datagrid fronts in with 8 RJ45 sockets. Problem now is because the backboxes are both loose and too close together, there isn't enough space for the fronts.
So, I want to put in a plastic "dry wall" back box. This is tricky as there is a single huge hole and the drywall boxes need to be secured to the plasterboard on both sides.
In my mind I know I just need a "double double" plastic dry lining backbox, but I can't find any! I can see plenty of 2 + 1 boxes, like this:

But I need a 2+2
Do they even exist?
