Your review: We have a climate controlled finished warehouse with about 10- of these units. These have replaced less capable homeowner type units. The key differences being the full length corner uprights - not multi-sectional. Heavy gauge steel and thicker deck particle board. Erected shelves are rock steady and never sag, even after several years of use.
Pros: Easy to assemble and make adjustments.
Cons: Heavy to move the incoming shipping cartons.
