Anyone cut the lip off a dry wall back box

[RobTi]

Have a few newly fitted back boxes and with the lip that sits on the face of the plasterboard it keeps my faceplates out from the wall (scolmore grid pro metal with a plastic back to them) so it’s either cut them or fit metal back boxes, so thought to ask on here if anyone had cut 5he lip off ?

 

[EFLImpudence]

Yes. It fell down behind the plasterboard.











No, not really, of course not.

score round the box with a knife and create a "trench" about 3mm deep for the lip to sit in then the accessory should sit flush

That's exactly what I've done in the past before. You can then paint the lip to blend in with the rest of the wall if you want.

If you cut the lip off, the back box could fall behind the plasterboard when you install it or replace the accessory in the future.

Can’t fall as I cut a square out of the plaster behind it(house was sheeted over years back when council decided to renovate)

Worried that the wings would burst through the plasterboard when fixing the face plate

You can get flush mount back boxes where they have no lip but instead you screw through wings with drywall screws to secure them.

or fit metal back boxes

How easy is this?

You used to be able to get lugs to fit metal boxes.

These ones say they are for flush/flat accessories if you don't want to cut the lip. Maybe give these a try.

I thought they had been discontinued but well done for finding them, needs a neatly cut hole though as there isny much cotact on the tiny "lip"
