It's really heavy duty, nicely painted, and makes fetching and storing weight plates a breeze. You can store 1" or 2" weight plates by using or not using the 2" heavy duty plastic weight plate sleeve adaptors. There are 6 of them.The 6 weight plate arms are ideal as the set of colored Olympic 2" weight plates I'm going to accumulate come in 6 weights. I'll be getting 2 weight plates each of 10 lbs, 15 lbs, 25 lbs, 35 lbs, 45 lbs, and 55 lbs, so one set of 2 plates at each weight for each arm on the storage rack.Two minor complaints: The washers labeled #17 had a bit of surface rust but since they are zinc coated, I'm not sure where the rust came from. And they accidentally gave me a #17 washer instead of the needed #16 washer, so I was short one #16 washer. I just did that nut & bolt without a washer rather than head out to the hardware store for one washer+.I will help you learn from a mistake I made. I tightened all the nuts & bolts up at the very top of the rack BEFORE I but my 45 lbs Olympic barbell in the barbell holder sleeve so I had to use force getting it in and out to put it up and take it out. I used leverage to force it into alignment to make that easier, but you'd do better to tighten up the top nuts & bolts on the weight plate rack LAST with the 45 lbs Olympic barbell put away in the barbell holder so you can line it up just right for yourself. Otherwise, it was very easy to put together, it took about an hour. I'm thankful I don't need to buy no more weightlifting equipment until next fall when I add the 3 heavier sets of Olympic plates, this equipment adds up.
