"I was nervous about using board-mounted boxes, having seen how some sockets get pulled about I thought they'd get dragged out of the plasterboard in no time. Finally I gave them a try (circumstances gave me no choice) and am kicking myself I'd not used them sooner. They have a generous flange on them, so the holes cut can be out by a few millimeters and you can still mount them square. The leads have been tripped over a few times and the plugs pulled out by the leads - but the sockets have stayed firmly installed. Impressed!"
"Used these loads of times for power or data/AV applications.
Very simple to install, only things to watch for are don't get to close to a stud or the locating lug won't be able to be pushed in and they can sometimes be a bit funny to get located properly if the board thickness is too much, i.e. if its had a very thick skim plaster.
"What a great product for plasterboard walls, simply draw around the base, cut it out using a drywall saw and slot in. The wings anchor the unit to the wall when the faceplate is screwed in. I wouldn't use anything else for drywall!"
