The shelves fit perfectly for my space. One of the metal ends arrived bent and I was able to bend it to the right position with pliers, but that cracked the white finish.  I found a pic online of a similar wall anchor since the ones included looked different than others I have used before.  I followed another reviewer’s suggestion to attach the hardware to the shelves but don’t tighten all the way. This allows one person to install the metal braces to the wall first and then fit the shelves in and tighten.
