Hyper Tough Black Plastic 4-Tier Shelving Unit, 280 lb Capacity, 56.2x30x13.8 Inches

Before you assemble it buy a cheap three dollar rubber mallet from Walmart. Yes you can. pound it with your hand and make it work. But it will never stay stable. It’ll always teeter totter. Then you’ll end up complaining that it moves which it does not. You need a rubber mallet and once you hear the crack that means that the tube has hit the top or I should say the bottom of the top hit it gently don’t go THOR on it! Headed gently first tested out I’ve gotten so good a simple anywhere between as little as 5 to 20 of these a year. I started gently then you’ll kind of feel if you grab the pipe on the bottom that is hitting the top or bottom of this assembly. Done and done.

this isn't going to hold a thousand lb and 20 totes but it worked perfectly in the place I needed it for. we used it in a barn to hold totes of bird seed and other things that I wanted off of the ground but not a project I wanted to spend a lot of money on. I think the best part about it was I was able to get storage within lugging a heavy metal filled box out of my trunk! it's so stinking easy to assemble that I actually had my 5 year old do most of it and he had a great time being helpful!
