DudeIts got like 4 bolts that go into the feet ....... did you read the manuel ?
you just need to buy longer bolts when the surface is thicker, don't over tighten or your screwed
or you can buy their expensive as hell slide system
I have a 63 quart cooler, it works great but does not cool to the advertised temperatures....
mine is set at 26 deg F and what I put in frozen stays frozen, what I put in unfrozen stays unfrozen.
