Can anyone suggest where I can buy a 16mm deep metal backbox for a
double wall socket? I've found singles with the required depth, but
not doubles.

Thanks,

Andrew

will a 16mm one take a socket as well as the cables from it? 16mm is
normally used just for a light switch. The smallest depth suggested for
sockets is 25mm - I've just measureed a spare MK socket I have and its 15mm
deep, A 16mm box would definitely be too shallow.

I doubt it.

And even that is a bit of a squeeze, 38mm is much better.

Wonder why the OP wants a 15mm double box?

MK certainly used to make plaster depth two gang boxes. Try somewhere
other than TLC. ;-)

a look at MK's own website shows the slimmest double box is 25mm.

Dave did say "used" to make.

Not surprised as a 6 gang switch would have a lot of wires to cram into
such a small space. But they did once make them. A 'Google' on plaster
depth two gang brings up a hit or two.

True, but he implied that if you looked beyond TLC, you'd find one.

Its to replace an existing 16mm box that has a missing tab that the socket screws into. It was like this when we moved into the house: I'm not completely sure why a 16mm box was used, but I suspect that there is a conduit (or even a pipe) a short was back in the brick behind the box. I don't want to risk excavating space for a deeper box. The socket seemed to fit ok, though it was tight. I didn't have any safety concerns. (Question: should I?)

If I can't find a 16mm box then I may try repairing the existing box with a tab taken from another box. Alternatively I'll fit a plastic box that projects out from the skirting: its concealed by a bed so this would be acceptable.

I have only ever seen a few in use. They were both used for double sockets
and one of them had a massive burn mark where the live cable was crushed
against it:-)

That would be my main concern with a 15mm box and a socket. 1 or
1.5mm is relatively flexible and a some what smaller diameter than
2.5mm.

With old sockets the wires generally came out of the terminals at 90
degress to the back of the socket. Fitting into a 15mm box would
force quite a sharp bend in the wire close to the terminal.

'Cause that is all the builders had left? Or is it a DIY job and who
ever did it didn't know any better?

Not likely to be anything other than brick in the brick. Even those
bricks with three holes down 'em aren't (shouldn't be...) used to
carry any services.

See other post.

I think you can get extension frames rather than having to use a 25
or 38mm surface box.

Pricey though.

I used the single gang version of one of those to fit a dimmer switch to
a 16mmm back box that wouldn't take the extra depth of the dimmer.
Painted the spacer the same colour as the wall so it blends in more.
