Can I use this grounding adapter?

Question

I have a fridge that needs a grounder but I only have a two plug outlet. The adapter says I need to s***w the metal part under the wall plate to complete the grounding path. My wall plate is painted over though. If I just plug in the adapter will it work?

Answer 1

Yes, it will work.  It would be good to scrape off the paint on the s***w and attach the tab behind it if possible.
