Plug followers are specialized components used in various mechanical systems and manufacturing processes to ensure proper alignment and operation of plugs or connectors. Typically made from durable materials such as metal or high-grade plastic, plug followers are designed to guide plugs into their mating sockets or receptacles with precision.

In the context of assembly lines or automated machinery, plug followers facilitate the accurate insertion of plugs into connection points, reducing the risk of misalignment and ensuring reliable electrical or fluid connections.
