There are six nuts that hold the face plate on. They are not very serviceable and took forever with my broken wrench. After I got off six from the one changer I noticed the two face plates were welded together. What a pain I have six more to go so I gave up. I liked how all the bottom nuts were all rusted.
The last picture is the almost free Rowe anti-security plate. I tested the new grinded plate on a spare cabinet that I have and it worked and lined up.
