Well I never thought I would need a storage rack of this magnitude. But here I am. This racking system is rated for 2300 pounds per shelf, measures 42 inches in depth, 12 feet in height, and 16 feet +/- in length. This is rack number 3 for shop storage. But its the first metal version in the racking system. I wish I could say this would be the last of them, but realistically I need another wall full. Except that wall will be 30 inches in depth and will run at least 16 feet in length as well.
