Just picked up a second rack, off craigslist! It's the same typical built rack with the concrete mixing bins. I got it for only $75 and it's like brand new.

Unfortunately, it's supposed to be 6 slots, but the bottom slot, you can't fit the bin in because it hits the FLOOR. I also had to drop the support slides down slightly, as the bins wouldn't slide into place. But that was a minor ten minutes of work with a power drill.

And it's NEW. Very sturdy too. The concrete bins are easily twice or three times the size of the bins in my 'used' rack. I'll probably be using them for grow out bins mostly, but also will be putting some breeders in. The wire is too small for food to be put in. I can either cut out squares and install bigger mesh wire for the "food spots", or just put food into the bins. To begin with, I'm just putting food into them.

And the 32 oz bottles fit THIS rack! And I'd only sold half the bottles I'd ordered, so I have EXACTLY enough bottles for all 5 bins! YEAH!! Did I mention $75? Yes? Okay.
