(1) The round cover won't fall in.
One day when I was leaving work at RCA at Lancaster, PA, There was a plumber crew opening a round manhole in the street, and I saw the cover fall in.
There were gaps in the flange.
They gave up trying to recover the lid, and parked the truck over the hole overnight.
