48" W x 24" D x 72" H Adjustable Height 5-Shelf Steel Shelving Unit Utility Organizer Rack for Home, Office, and Warehouse, Black

The assembly had a couple of annoying issues. Most concerning was a layer of iron dust over everything. Hands were black after assembly. I needed to clean all the wire shelves before placing items on them. During assembly, as you lock pieces together, they frequently shift/disconnect while hammering other pieces into place. One of my shelves had a snapped support and would not lay flat. Placing the shelves is also tricky.

This product is similar to other metal shelving units I have used in the past such as the chrome ones with the plastic pieces you can adjust every inch to customize your height of the shelves. These work instead by the rails the shelves sit on into holes in the post and can be hammered down to "lock" into place. It works quite well and as long as the entire unit is level. It feels sturdy enough to use for medium use storage (I store bins up to fifty pounds with heavier bins on lower shelves). The main drawback I have is the shelves sit on the rails and don't sit the most flush with the rails so when placing items on the shelves there is potential for things to snag on the shelves. This would not prevent me from purchasing these shelves again in the future and if I do have a future need for more I will try to purchase the same shelving unit.

This unit's one-page assembly instruction includes the necessity of having two people assemble it. There's a good reason for that. I started assembly by myself, only to find myself at a dead end until my daughter came over and helped me finish it.I had to use zip ties to keep the top and bottom frames together while putting in the wire shelves to make sure the rivets didn't pop out of the slotted holes. There needs to be a spring locking device in the smaller slotted hole to hold them in place.Then came the worse part - getting black paint all over your hands while handling the wire shelves. The paint they used just came off on anything that touched it. Sorry, no pictures. After the shelves were in, I used an old towel to clean off what I could.

It will have to do. Even tapping in the sides, they kept popping off and didn't line up correctly. Pretty flimsy for a 5 tier rack
