I bought two of these planters for a deck remodeling project.  I bolted them to the edge of the deck and put rails on either side.  The planters are very study and work perfectly as part of the rail system. They look beautiful planted up with flowers.  
The shipping company should be instructed to avoid turning the box upside down. The shelf of one of the planters shifted and damaged the styrofoam liner.  It was easy to replace though.
