Buy this if you want a good product at a good price due to minor manufacturing flaws. It may not be the best choice if, say, you run an industrial meat packing plant — but if you are you are probably not even reading this review because you are ordering from ULine.Everything was as advertised, but you could tell these were slightly off-spec factory seconds. There were signs of surface scratches and minor corrosion in some of the metal parts, and misplaced through-holes in the PVC strips.Reviews mentioning severe off-gassing are absolutely correct — do not install these inside a living space. They were perfect for my garage. The supplier tried to turn the stink into a feature by saying they are packed “fresh” from the factory. These aren’t fruit. The supplier is saving money by not doing a bake-out to remove the off-gas before shipping. Theses have the appearance of marginal quality-control failures sold out the back of the factory to recoup the scrap costs. Great if you are a consumer who is not too picky but wants industrial-strength parts at an affordable price.
