The rack is made of 1x4's, 2x2's, and 1x2's that are.......oh you mean the ARS rack

its the 10 tub rack system from ARS and its AWESOME! if I ma not mistaken they are 995.00 plus S&H. I like the single rack much more than the 3 rows personally. I find the tubs in the larger racks tend to get wedged between the sliding rails much more often when taking them out. Not a major issue, just thought I would mention it
