Metal backbox connectors for a row of single sockets

Dec 17, 2021 Last reply: 4 years ago 21 Replies

Has anyone used these metal connectors for joining metal backbox connectors to make it easier to have a row of single sockets exactly inline ?.

I'm sure it used to be possible to buy brass threaded 20mm connectors to do this, a bit like the 20mm end connectors for round plastic conduit that screw into a knowckout, but I can't find them anymore.


Two male bushes and a coupler are the usual way, if you don't want to adjust the distance.

But who makes them ?. I'm sure it was possible to buy such an arrangement that allowed single back boxes to be fitted in a line with the correct spacing just like a dual/single combined backbox allows. I.e. You could make a four-in-line row of sockets without any gaps between them.

I used them and sorry to disappoint but you can only link two boxes together. They work by the small bent piece fitting into the hole pressed out to make the fixed lug on a back box and cannot be used on the movable lug side.

Unless you can find boxes with two fixed lugs I am afraid the limit is two.

Ok, thanks. What you show is the arrangement I intend, but a group of immediately adjacent single sockets that are nicely inline.

I need to choose backboxes carefully then

Just one other gotcha they work with white plastic front plates which are a standard size but if using metal front plates especially low profile types they may not work, you would have to check the various manufacturers data sheets as they all vary in size. The Volex ones you see are OK.

Yes, I have seen that warning on the ?tlc site that sells them.

PS I would have run a bead of magnolia decorators caulk vertically down the metal spacer to match the surrounding wall colour.

PPS Interesting egg stand. How far up does it go :-)

I'm sure I have seen plastic spacers that look like conduit and connect the round holes, but my googling skills aren't working.

The wall colour is just temporary as can be seen by not so smooth plasterwork. Eventually that section will be covered with a splashback.

The egg stand is 53cm tall and holds a dozen eggs in a spiral. I would have to go back through SWAMBOs Amazon purchases (and there have a lot through the pandemic) to get the link if you are interested.

I am not aware of plastic spacers that would give you the necessary spacing between boxes which if I recall correctly would be in the region of 14mm. However, you could use these;

In conjunction with these to hold boxes the correct distance apart and at the same time allow you to pass cables between boxes;

There would be some protruding into the boxes if not cut down and obviously no grommet maybe Adam can advise regards standards.

If threaded conduit is taken into a box then the inside should be terminated in a female bush and not a locknut

Then I shall do it for you Sir

They ought to make it clearer that's £3.75 for ten.

Thanks. That's the one. :)

I tried googling for backbox spacers, but it produced only the 1G and 2G ones that go on the face of the box to make it deeper.

Well I found it by googling for "back box connector spacer" but it took me a while to find the correct combination of words get there for exactly the same reason.

Never used them, never seen them before.

But they look bloody useful.

Have a good Christmas fella

And do you remember the trouble I had in Leicester with the conduit couplers and 35mm deep back boxes?

Dual back boxes have been around for years

Having a f****ng nightmare at a house this week where the back boxes are too close to each other to swap them to metal ones.

When I moved into this house I made friends with the bloke that lived across the road. Retired and a nice bloke with time to spare.

He made me a load of 13mm balsa wood spacers that I used to distance the back boxes.

does say 10 x units per pack and it has a link for the most unenthusiastic sales video I have ever seen.

:-). I think I will use a length of 2x1 and drill holes exactly 1 inch apart where there are adjacent boxes and attach the four metal boxes in a nice straight line, then fit all four in one go.
