Electrical – How to make a receptacle box flush with wall after it has been installed

electrical

blue box
We have two receptacle blue boxes installed. Both were going to be in back splash wall so contractors had them not flush with the wall, I guess accounting for the thickness of the tiles.

Long story short. We're not gong to have a back splash around one of the blue boxes.

How do I make this blue box flush with the wall? Also you can see that the blue box is not evenly inset. Left side and top sticks out more than the right side and bottom.

Do I just trim the plastic down so that it is flush? Does that somehow make it not up to code?

The box looks like this type of adjustable depth box. Try tightening the screw but if the box doesn't move you should cut away adhering drywall mud or calk, until it does move. Given the metal bracket which supports the box it is surprising that it is not square to the wall. Maybe it will straighten as it is pulled into the wall, but if it doesn't it will be OK to use. Get some of those plastic shims for receptacles and put the right number on the screw of the receptacle to put it in the plane of the wall.
