Great shelving units
Your review: Easy to assemble and very strong. You can either order it with shelving or save on freight and provide your own. I really like that you can put in short screws from the underside of the supports to "lock down" the shelves so they don't move on you. These come in many different lengths, widths and heights to fit almost any space that you might have. I have purchased several of these units in different sizes for different needs and have been very satisfied with my purchases.
Pros: Easy to assemble. Only really large units require multiple people. Very strong. Very economical.
Cons: Freight can be more than the units themselves when getting units 8 feet long or longer with deep shelves. Recommend you buy plywood from local lumber store and make your own.
