Not impressed
Not impressed; doesn’t look as good as in the photos. Also, the one I received it not level? I don’t know if it was stored on a shelf incorrectly or it’s it’s a design flaw.

Great for shed organizing
Size: 4.5", Style: Open, Size: 4.5", Style: Open
We recently upgraded to a conex/shipping container/metal shed and needed a way to organize all of our yard tools. These work great, the weight holds a lot of items, could be a little longer but we were impressed with them holding everything for over a month now and not moving.
