Hafele definitely makes this--I'd be surprised if Rev-a-Shelf doesn't also. Their specs call for 24" height for the 50 qt can (which gives you a 6" drawer above if you have standard cabinets).

We have a Rev-A-Shelf pull-out trash, 2 x 13 gallon cans, with a full drawer above it.

Yes! You can fit the rev a shelf double 50 qt can pullout with a drawer. I expected not to have a drawer, but when the hardware came in, my builder said he could fit a drawer over the trash pullout, so we added it. I can take photos in a few days next time I'm at the house if you so desire.

Thank you all. This helps me when I talk to our GC next week. Thanks so much for the pictures too. :)
