I researched and compared all the competitors in this class of garage storage racking.  Gladiator is clearly the winner!  The rack is well packaged, simple to install, very sturdy, and has a super tough finish.  This thing holds a lot and the metal gauge feels heavier than the others.  Also Gladiator has cross members on each shelf to add strength and prevent the side rails from bowing out.  The other brands do not have this.  

It was great to all this stuff off the garage floor.  I am really happy with my Gladiator Mega Rack!  Go with Gladiator and you will not be disappointed.  

Tip:  Cut the box top and bottom down the middle and to length and you can place the cardboard on the wire rack shelves to prevent small parts from falling through
