What is the minimum strength rating listed for both steel and aluminum carabiners?

• A. 3,000 pounds
• B. 5,000 pounds
• C. 7,500 pounds
• D. 10,000 pounds

Answer: (B)

The key idea here is understanding safety ratings for gear. In this ropes course context, carabiners must show a rating that can safely handle the loads they’ll encounter, including dynamic forces when people move and catch on equipment. For both steel and aluminum carabiners, the minimum listed strength is five thousand pounds. This means any carabiner used should declare at least that rating to meet the course’s safety standard.

Why this fits best: five thousand pounds provides a practical, reliable safety margin for typical course loads and activities. A rating of three thousand pounds would be insufficient for the dynamic and multi-person scenarios you might encounter. Ratings higher than five thousand pounds exist, but the question asks for the minimum, so five thousand pounds is the correct baseline.
