The piece does what I want it to on a long wall.  I did not want to clutter up the wall with multiple hangings.  The piece has one hanger location about in the middle.  It is a washer welded to the art.  The washer has a rather large opening making it necessary to find a screw with a broad head or to place another washer on the screw when hanging the art.  Also, it would be nice if the company offered some suggestions for wall anchors.  I settled on a metal anchor that contracted inside the wall allowing me to remove the screw and add the necessary washer so the screw did not go through the large hole provided by the manufacturer.  The screw needs to extend about 1/2 inch to accommodate the depth of the art piece. I am sure some lawyer told the company not to offer suggested resolutions to the art hanging issue.
