Which knot is used to create a friction hitch for ascending in rope access?

• A. Prusik knot
• B. Figure eight knot
• C. Overhand knot
• D. Bowline

Answer: (A)

The friction hitch used for ascending is the Prusik knot. It’s a small loop of cord tied around the main rope in a way that because the loop is slightly smaller than the rope, gravity and load cause the hitch to grip firmly as you pull upward. When you ease off, the grip relaxes and the hitch slides, letting you move up the rope. This makes it reliable for ascending in rope access and works well in wet or icy conditions. It’s also easy to inspect and re-tie. The other knots don’t provide the same adjustable grip around the rope. A figure-eight serves mainly as a stopper or anchor and doesn’t grip to climb. An overhand knot is a simple stopper and can bind, making movement difficult. A bowline creates a fixed loop and doesn’t offer the sliding, grip-and-release action needed for ascending.
