I purchased the Heavy Duty Mega rack to help organize my basement.  I was hoping to use if for a number of boxes and other items and I was shocked with how much I was able to fit on the rack.  As I continued to load the rack, it seemed like there was always room for one more item.  The strength of the rack was also very impressive.  I know that I could easily store much more weight on each shelf.  I am already considering another rack for my basement as I think I would be able to organize the entire basement with just 2 of these racks.
