Bin Open Shelving
Your review: The bins that come with this particular shelf system are large enough to accommodate the large diameter stud bolts and nuts I needed to organize. When putting the shelves together I thought that they were a little flimsy, but once we put some weight on it, the unsteadiness of the shelves stopped. It now has a few hundred bolts/nuts on it, and it is very steady. I should have ordered the bin dividers with the unit, but they were available afterward. Global Industrial also sells bins that can be swapped out to change the configuration. I am very pleased with this.
Pros: Versatile bin arrangement, decent cost
Cons: The shelves are a little wobbly until they have some weight on them.
