If you are working with a finished wall, be sure that whatever you are using
goes past the finish and into the structure. In my at-work office, a
bookcase was mounted onto a finished block wall with the expanding lead
anchors -- but they were only into the stucco/morter finish coat and not the
blocks themselves. It stayed for years, then let go with a bang -- landing
on my chair. Fortunately, this happened before I arrived. Charles
