Every other answer to a question that involves electrical boxes references the advantage of metal boxes over plastic (old work) boxes. It is claimed that they are very flexible to mount but I don’t see how.
If I have the choice , I’d go for metal. Right now, I have two holes open:
- A hole for a light switch where approximately 1/2”-1” under the hole is a horizontal wood beam. I could attach the box there but I would need a spacer between the wood and the box, such that the box is at the right height.
- A hole for a ceiling light with a beam next to it. But the light should be a few inches off the beam. Again, a spacer would be useful (I know the poles that attach in between two beams)
Are there “spacers” for mounting electrical boxes? Is it possible to install them in an “old work” setting as described above?
Note, my question is for lath & plaster which is very hard to patch so I went to avoid larger holes than necessary
