What component must be present in the WPFR device to function properly?

• A. Cleat
• B. Carabiner
• C. Harness
• D. Spring

Answer: (A)

The main thing being tested is how the WPFR device controls rope without slipping. The cleat provides the essential friction point that the rope sits against or around to jam and hold the line in place. This keeps the rope from sliding and allows the device to control movement, whether you’re feeding rope, lowering, or arresting a descent. Without that cleat, the rope wouldn’t be secured reliably and the device wouldn’t function as designed.

Others—carabiners, harnesses, springs—play important roles in climbing and rescue systems, but they aren’t what the WPFR device relies on to do its core job. A carabiner is mainly for connecting pieces, a harness is what the climber wears, and a spring is part of various mechanisms, but the critical component that makes this device work is the cleat.
