Carabiners used in climbing should be rated to handle how many pounds?

• A. 1,000 pounds
• B. 2,000 pounds
• C. 5,000 pounds
• D. 10,000 pounds

Answer: (C)

When evaluating climbing gear, the important idea is that equipment must withstand forces far beyond a climber’s weight because falls create dynamic, peak loads. Carabiners used in climbing are designed with a high major-axis strength—roughly 20 kN—which is about 4,500 pounds. To ensure a safe margin for these forces and for practical use, manufacturers assign a working load limit around 5,000 pounds. This means the carabiner is rated to handle up to about five thousand pounds without risk of failure under normal use, even when dynamic loads from a fall are involved. The other options are either below what standard climbing carabiners are designed to carry safely or exceed what the gear is meant to sustain, so they don’t reflect the typical safe operating capacity.
