I have set up all I need of this size so I've reduced the price on these.
This is a used 48" x 48" x 7' tall section of medium duty rivet rack shelving. No chipped paint no rust. Bolt less assembly so goes up quick. Each shelf can hold 400 lbs. You'll have to get a sheet of OSB for the top and bottom shelf and cut it in half. Disregarded the pictures for the parts count. Here's what you'll get. (4) 7' uprights. (3) wire shelves 48" x 48", (4) bottom perimeter bracing bars, (12) intermediate/top crossbars. I have 2 of these sections. If you want 2 sections it's 350.00
See my other listings for 24" x 48" x 7' tall rivet rack, 18" x 48" x 36 and 48" tall patio/greenhouse/garage storage shelves, 24" x 60" x 74" high Bakers rack shelving. OOAKWW
