What is the NFPA load rating for carabineers?

• A. 6,098 lbs
• B. 8,992 lbs
• C. 9,000 lbs
• D. 7,000 lbs

Answer: (A)

NFPA load rating reflects how much force a carabiner is designed to withstand along its major axis in a life-safety rope system. For NFPA-compliant carabiners used in emergency services, the major-axis strength is specified high enough to handle dynamic rope loads, and the commonly cited figure for this rating is about 6,000 pounds (roughly 27 kN). That’s why the option of 6,098 pounds aligns with the typical NFPA rating used in standards and many manufacturer specs. It’s important to note this rating applies to loading along the long axis; cross-loading can dramatically reduce strength, so avoiding loading the carabiner in non-major-axis directions is part of safe rope work. The other numbers aren’t the standard NFPA major-axis rating for carabiners in life-safety applications.
