The cleat must be present in the WPFR device to work properly.

• A. The rope guide must be present
• B. The cleat must be present
• C. The brake knob must be present
• D. The swivel must be present

Answer: (B)

The essential idea tested is that a secure locking mechanism is required for the device to function safely. The cleat provides the positive lock that holds the rope in place under load, allowing controlled movement and the ability to arrest motion when needed. Without the cleat, the rope can slip or release unexpectedly, making operation unreliable and unsafe. The other parts—rope guide, brake knob, and swivel—aid in routing, friction control, and preventing rope twist, but they don’t provide the necessary locking action on their own. So, the cleat must be present for proper operation.
