The flat steel wire or fiber cord that is pushed or pulled through a conduit is called a(n) _____.

The term used to describe the flat steel wire or fiber cord that is pushed or pulled through a conduit is known as fish tape. This tool is specifically designed for the purpose of running electrical wires through walls, ceilings, and conduits, making the installation process more efficient. Fish tape is typically flexible and can navigate bends and curves within the conduit, allowing for easier pulling of the wires without damaging them.

While the other terms may refer to tools or concepts used in cabling or related tasks, they do not specifically describe the purpose and function that fish tape serves in this context. For example, a wire guide might refer to a device used to help direct the wire but does not perform the same function as fish tape. A conduit rod is often used for other types of tasks related to installation or maintenance rather than the specific action of pulling wire through the conduit. A puller line, while it may seem similar, is not as widely recognized or standardized as fish tape in the context of electrical and cabling work. Thus, fish tape is the appropriate terminology for this scenario.
