Repairing an electrical back box

Hi,

We got some work done and the person doing it broke a tab in one of the electrical back boxes. It's not currently a big deal as the remaining screw is holding tight and the plugs using it are not frequently changed.
However, I would like to repair it.

There seems to be a number of ways of doing this from tapping out the back of the box and using an extra long screw to putting on a new tab with chemical weld (J B Weld).

However, I've noticed on a popular internet auction site the following two items:




Has anybody tried either of these on steel back boxes or recommended either of them?


Thanks.

I've never seen those before .
is it on a stud wall or a masonry wall?
If its stud sometimes you can disconnect everything and drop the box into the cavity then push the cables out of the way,
Wiggle a new box into the hole
then once its in the wall get the cables in and move it into position.

If its masonry you can drill a 6mm hole through the backbox (drill the steal with a HSS bit first) where the faceplate screw would meet the back box.
Put a red plug in and get the right length 3.5mm machine screw and go through the faceplate and into the red plug.
So the 3.5mm socket screw is effectively screwed into the wall not the box.

Masonry wall.
These would have been a simple fix.

I'll try door number 1.
