I loved the wood rack and it seems very solidly made.  However, the dimensions advertised said 4" depth but that is the total depth from the front of the wooden shelving unit to the back - including the depth of the wood itself.  The shelf opening is only 2-3/8" which is not large enough to hold most of my spice jars/containers.  I was very disappointed.  If they had an option with larger/deeper shelves, I would order it again.
