What device assists in advancing a cable within a conduit?

The correct answer, which identifies the device that assists in advancing a cable within a conduit, is a tugger. A tugger, commonly known as a cable tugger or cable puller, is specifically designed to pull heavy cables through conduits by providing the necessary force while minimizing the risk of damage to the cable itself. This mechanical device aids in the pulling process, especially when dealing with long runs or multiple bends in the conduit, making the task safer and more efficient.

The tugger offers several advantages, including its ability to maintain a consistent pulling tension without the manual labor that would otherwise be required, thus preventing potential physical strain on the installer and reducing the likelihood of improper installation due to human error. This makes it an essential tool in the installation of cabling systems.

In contrast, a pulling eye, while also related to cable installation, is used to create a point to which a pulling load can be attached rather than actively pulling the cable itself. A jack stand is primarily used to support or stabilize equipment and is not directly involved in the process of advancing cables through conduits. A guide wire assists in orienting or directing the installation, but it does not provide the pulling capability that a tugger does. Each of these other tools serves
