16mm deep double socket backbox

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 complet= ely 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, thoug= h 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 proj= ects out from the skirting: its concealed by a bed so this would be accepta= ble.

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

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.
