The outer casing is usually made from metal or hard plastics, which ensures a secure fit within the housing or bore.

Despite their importance, manhole covers can often go neglected, resulting in deterioration over time. Various factors contribute to this issue. First, the sheer number of manholes in a city creates challenges for regular inspections. Municipal agencies may lack the resources—both financial and personnel—to effectively monitor every manhole, especially in larger urban settings. Furthermore, the underground utility networks can be complex, making it difficult to ascertain the needs of specific manhole covers without extensive investigation.
