Yes, it holds a single 8.5" diameter 5 gallon corney keg.
The 2 gallon cooler is very secure right now, though it can be removed with some force.
On the Igloo cube lid top layer, I cut the hole a few centimeters shy of the 2 gallon cooler's red section diameter, which is slightly larger than the white section (where the handles mount and lid threads are).
The bottom layer of the cube lid is cut a few centimeters short of the 2 gallon cooler's white section diameter.
So, the 2 gallon cooler slides in (with a bit of force) until the red part hits the bottom layer of the cube lid, which ends up being enough height inside to accommodate the keg, hoses, and faucet.
