When i bought my house the previous owner left a bunch of those in the garage, given they look like their 25+ years old, but they are very flimsy. If your has better angle iron than mine it might be alright but the ones I got I had to screw to the wall to keep from tipping over if anything with some weight was put on them.

If you already bought it and using it, great it working out for you, like I said mine are really old, but exact same style.
