The cord used in pulling systems to move cable through spaces is known as what?

• A. Tension line
• B. Nylon cord
• C. Rope
• D. Fish line

Answer: (D)

When pulling cables through walls, ceilings, or conduits, you need a line that can be threaded through tight spaces and then used to pull the actual cable. A fish line is designed for this purpose: it’s a lightweight, flexible line that can be easily guided through confined passages, then tied to the cable so it can be pulled back through. This makes the installation smoother and minimizes snagging or damage to the cable.

The other options aren’t as well suited. A tension line isn’t a standard term for this task and doesn’t imply a line intended to thread through spaces. Nylon cord is generic and can stretch or fail to handle the pulling load, while rope is typically thicker and harder to thread through small openings, increasing friction and snag risk.
