I doubt it. It was advertised that way but these things never hold full capacity in any practical way. I suspect it could have come close with cases stacked on top of the shelves rather than a single layer of bottles and cases stacked on the floor against the wall opposite the door.
I never had more than 1500 in it and there were still a few dozen open slots. IIRC there were slots for about 1600, plus room to stack on top. Mags and fat Champagne bottles had to go on top.
