A round manhole cover cannot fall through its circular opening, whereas a square manhole cover could fall in if it were inserted diagonally in the hole. Circular covers don't need to be rotated or precisely aligned when placing them on the opening. A roundmanhole cover is easily moved and rolled.
A manhole (alternatively utility hole, cable chamber, maintenance hole, inspection chamber, access chamber or sewer hole) is the opening to a confined space such as a large vessel, a shaft or an utility vault (often used to house an access point for making connections, inspection, valve adjustments or performing maintenance on underground and buried public utility and other services including water, sewers, telephone, electricity, storm drains, district heating and gas).
