The file caddy was exactly what I needed so I could move my cabinet around. The screw heads could have been flat but they are rounded and the cabinet doesn't fit all the way down but it still works.
I had found a two draw metal file cabinet at a thrift store. I painted to blend in with my living room and wanted to be able to move it around for cleaning. This caddy was EASY to put together. So now my cabinet doubles as an end table and storage.
