Two sets of industrial shelving from a manufacturing facility that was closing down. 8 feet wide, 6 feet tall, and 2 feet deep, rated to over a ton (allegedly). I bounced up and down with my feet on the bottom shelf at the middle and there was zero perceptible flex. Of an original 8 when they posted the ad five days ago they had two left. $40 each. I purchased both, one for my garage and the other for my brother’s workshop. Good buy.
