Hi there. Just a quick question about fitting a box into a dry lined wall,
so I can fit a TV socket faceplate to it.

How do these plastic backboxes actually secure. It looks like you just saw
a square hole in the dry lined wall and put the box into that, then mount
the faceplate. Surely there is more to it than that? Wouldn't they pull
out easily?

Thanks in advance.

The dry line boxes have tabs that are attached to the faceplate screw
fixings so that as you tighten the faceplate the box clamps to the
plasterboard. The tabs retract to allow it to be fitted into the hole. Are
you sure you have seen the right type?
