Unfortunately the plans I used didn't allow any extra width to add in bigger rails, I didn't even think of that in the first place. I originally built them to raise ASF but gave up on them and now I raise regular hooded rats. Which are A LOT heavier than ASF colonies. Which I assume is why I had the bin drop out. Also the bins gradually get heavier (obviously) from all the food, poop, pee, water, etc.

I wish I thought of this when I built them, because now I can't go back and build lower supports because there isn't enough room between the bins. Oh well!

Yours looks great, though!
Thank you! The next one I make I am going to use all 2x3, they are the same price as the 2x2 where I live.
Thanks to everyone for the advice!
