What is the safety for a butterfly knot?

• A. Locked carabiner
• B. Non-locking carabiner
• C. Figure eight knot
• D. Rope grab

Answer: (A)

When a butterfly knot is used as a midline or anchor point, the safety measure is a locking carabiner. The butterfly knot creates a stable looping point that can take load from multiple directions, and clipping a locking carabiner through that loop keeps the knot from opening or shifting under load. The lock prevents the carabiner gate from accidentally opening, which would allow the knot to fail or the rope to slip. A non-locking carabiner could unclip with movement or impact, compromising the setup. A figure eight knot serves a different purpose and is not the safety device for this knot, and a rope grab is a separate piece of equipment and not the safeguarding element for the butterfly knot.
