Where are handholes primarily utilized?

Handholes are primarily utilized on lateral two-way duct lines, which serve as access points for maintenance, inspection, and repair of underground utility systems. These structures enable technicians to enter underground pathways easily, facilitating work on conductors or cables installed within the duct lines. Their design allows for quick access to the network of utilities without needing extensive excavation, which is essential for efficiency and safety in managing telecommunications, electricity, and other infrastructure.

While handholes could be found in power substations, residential homes, and main feeding lines, their primary function aligns more closely with lateral two-way duct lines, where convenient access is necessary for ongoing service and maintenance operations.
