Isn't it more than that, förhöjningsring and longer screw.
Best answer
If you place a gles across the glesen with perhaps a couple of masonite pieces between (to adjust the height) and screw the box into it, you can get it positioned so that the box is a few mm inside the plasterboard, which is approved. Much cheaper than extension rings.
