I just got back from HD to measure the inside depth. It was 27" 3/4, but I think the bulge in the lid will make it 27" 1/4. Is this tall enough to fill ball lock kegs without a collar? I want to be able to wait a while before I build a collar. When I called mlhs they thought that would be too short, but they sounded unsure. Is the height of different ball lock kegs variable? I haven't ordered a kegging system yet, but I don't want this deal to pass me by. Thanks for the info.
