Round manhole covers are generally used over square manholes because they cannot fall through the manhole openings. There is a chance that if square manhole covers are used they can be turned at an angle and fall through the manhole opening. Round manhole covers can be moved more easily as well.

They are called man holes, or manhole covers.
