Why are most manhole covers round?

Manhole covers are round because a round cover cannot fall through its circular opening. The manhole cover rests on the frame seat; therefore, the diameter of the frame opening is smaller than the manhole cover. Whereas a square or rectangular manhole cover may fall through an opening if turned diagonally in the hole. It is also easier to dig a circular hole. Round covers are easier to machine on a lathe. A round manhole cover can be rolled, which makes it easier to move if needed. However, any customized shape is available from us.
