What is the purpose of a portable conduit fishing system?

The purpose of a portable conduit fishing system is to blow a pull-line through the conduit. This system is specifically designed to facilitate the installation of pull lines within conduits, especially in scenarios where running a line manually would be challenging due to the length or complexity of the conduit run. By using air pressure, the portable conduit fishing system efficiently transports the pull line through the conduit, making it easier for technicians to later pull wiring or cables through.

This method is beneficial as it saves time and labor compared to trying to manually fish a line through the conduit, which can be difficult, especially in longer runs or when there are multiple bends in the conduit. The other options listed, such as drilling holes, measuring trench depths, or sealing conduit ends, do not align with the primary function of a portable conduit fishing system, which is focused on the efficient transfer of lines through conduit systems.
