What is a tool used to assist in installing a pull line or pulling in a cable?

Fish tape is a crucial tool in the process of installing cables, particularly when it involves pulling a line or cable through conduits, walls, or other intricate paths. It is a long, flexible metallic or fiberglass tape that can be guided through tight spaces, allowing technicians to attach a pull line or cable to the end of the tape and then pull it back through the conduit.

This capability is particularly valuable in situations where direct access to the cable path is limited. By using fish tape, technicians can efficiently navigate the corners, bends, and various obstacles that may be present in the installation route. The smooth surface of the fish tape minimizes friction, which helps in reducing the effort needed to pull cables through.

In contrast, other tools listed serve different purposes. A pulling hook is suitable for securing a cable, while a cable tray acts as a support system for holding cables in place and does not assist in pulling. A conduit bender is used to shape conduits but does not play a role in pulling lines or cables. Thus, fish tape stands out as the right choice for assisting in installing a pull line or pulling in a cable.
