This item is very nice tubular steel.  I was pleased to see it on the Program because I really needed one for my garage sale.  It's 100% better than ones I've bought in the past because they didn't last very long at all.  There is one drawback, for me that is, it doesn't have wheels.  I do believe that wheels can replace the levelers...the screw in caps.  The one is very well made because each pre-drilled hole has a metal piece that keeps it from shredding out.  This would be a good purchase.
