For pulling cables into a conduit or duct, which type of rope is recommended?

• A. Strong nylon twine
• B. Low-stretch rope such as multiply or double-braided polyester
• C. Polypropylene fishing line
• D. Hemp rope

Answer: (B)

When pulling cables through conduit, you need a line that won’t stretch much and can handle the load. Low-stretch rope, like multiply or double-braided polyester, provides high tensile strength with minimal elongation under tension, so you can pull the cable smoothly without the line length changing or the rope failing. Polyester rope also resists abrasion, handles moisture well, and has a smooth surface that reduces snagging on conduit edges, making it reliable for pulling through tight spaces. The other options don’t fit as well: strong nylon twine isn’t designed for high-tension pulls and can still stretch or fray; polypropylene fishing line is lightweight, slippery, and not rated for heavy pulling; hemp rope tends to absorb water, rot, and has inconsistent strength, which makes it unreliable for conduit work.
