Broken Back Box for twin socket

[dazooboo]

The metal back box for a client has one of the threaded lugs missing. The box is deep in the wall (tiled over twice) I need to use 3 inch screew to pick up the other lug. Any ideas, tricks of the trade, or products on the market to fix the problem of the missing lug?

If the missing lug is one of the type that are held in by clips,Remove another from a spare backbox if you have one and then repinch it back in with some pliers or tap back in with back of pliers.

 

[steptoe]

or drill and tap back of back box and use an extension stud.

 

[Bacon]

Or as Steps says do that.

Or a bit of fiddling with a hacksaw, a bit of lateral thinking and an MK 3840 bracket... :coat

I had a similar situation a couple of weeks ago. The metal box was so deep that I was able to fit another 25mm box on top of the old one, drilling two holes in the old box with a metal drill before using a masonry drill then 3 inch screws plus through crimps to extend cables- job done.

I know I have replied to this thread,

But its like so many others and is simply asking for an easy answer to an easy solution that would be learned on a proper apprenticeship.

Im having a lot of thoughts right now........

35 years on and I had never thought of that!!!!

Up until now it has always been...3840 bracket, or drill through box into wall and red plug/screw [if brick wall]

Somebody once said 'every day is a school day', same bloke also said [i think] 'nobody knows as much as all of us'

...anybody know where I can get a 'long' M3.5 tap?...may as well be prepared! got loads of standard ones but with my luck ............ :coat

Don't fancy your chances of finding a long tap. A long tap wrench is the answer.

qvs sell a long 3.5mm tapper

 

[Sidewinder]

You could always weld an extension onto a std. tap?

There is no such thing as a proper apprenticeship nowadays! I think so many companies have had to specialise in different areas that few people have a good general knowledge. Apprentices are given the menial jobs and 'trainers' dont have time to teach them to be electricians.

Got a tap wrench that is 18" long! Trouble is that the chuck is too bulky to get tight into the side of the box. Ging to look on QVS now......... :coat

 

[Sidewinder]

I do have an 18" tap wrench, the chuck is not that big!

Though it depends on how far into the corner you need to get!
