The metal back boxes are used in solid walls, such as stone, brick and breeze block walls. The cut-out for these metal back boxes are normally chiselled out of the wall material. The lugs on these back boxes are metal and normally fixed. As you tighten the screws on the face plate, it fits the face plate tight against the wall.
