Quantum Medical QBR-3619 Stainless Steel Lab Bench Rack - Heavy Duty Laboratory Equipment for Medical, Research & Clinical Use

The bins are okay, but you can't put any weight in them if they are hanging from the back rack. They hang down and look ugly. (each hangs down based on how much weight you have in them.) For example a box of fender washers in one, a box of 1/4" x 1" bolts in another and a box of nuts all weigh different amounts and the bins will hang down a different amount. I ended up scrapping the rack and just put them stacked on top of each other and that works very well, however I bought the system to get them up off my bench and on the wall and because of that I rate it only 3 stars. Look for a design that supports the bins front and back.If you are using them for light products like buttons, bobbins, needles, candy, marbles, toys, etc then they are very good. But for heavy objects, you'll end up stacking the bins on each other.
