Engine Rope Complement: What is the length of the green Prusik Cord?

• A. 56 inches
• B. 70 inches
• C. 80 inches
• D. 90 inches

Answer: (B)

The key idea is that the Prusik cord length in an engine rope kit is chosen to give you enough material to form a reliable friction hitch on a range of rope diameters while still staying compact for quick access. A 70-inch green Prusik cord provides enough slack to wrap several times around the main rope and still have tails for tying and handling, which makes the Prusik usable in various rescue or ascent/descent scenarios. If it were much shorter, you’d struggle to get a secure hitch and have usable tails; if it were much longer, it would be bulky and cumbersome to store. That’s why 70 inches is the standard length for this kit.
