Do you mean 2g and 2x1g all as one box?

or

You might be able to join some metal back-boxes together using 20mm conduit bushes and nuts at a push (with some more nuts as spacers, so the 1g accessories fit side-by-side OK), but if you start with most together like this it is only a 1-gang 35mm-deep box to be added:

If it has to be plastic for fitting to plasterboard easily then you are probably out of luck.

IMO 2 x 1-gang accessories jammed up together always look bad. Gonna be even worse with a 2G in the mix as well. Gaps are needed.

Go with separate boxes. Joining with conduit bushes is good, but use couplers to space them.

they do longer ones for oversized metal faceplates that need a little more space between the boxes. think the short ones are about 16mm and the longer ones 22 -25mm.
 
That's got to be another Dragons den thing;

Quote from the website;

As with all the best ideas, the Spacer Connect is simple and often followed by the 'why didn't I think of that???'!

Answer is easy as usual,, the price they have to be in low volume production,

Price is per 10.​

15mm Spacer Connect £3.75​

35mm Spacer Connect £4.25​

Conduit Connect £4.30​


 
It’s for a customer who insists on having faceplates with no gaps. Just want to get it spot on
I would contact Hamilton Litestat and get something made up then , have had some stuff made in the past and customer was very happy.
Prices can be high thou , some of the custom pieces were £100+

Where does galvanic corrosion arise in electrical work ? Is it mostly copper-aluminium or are there other metal combinations to watch out for ?
