What is the rating for a standard carabiner?

The standard rating for a typical carabiner used in climbing and rescue operations is indeed 11,000 pounds. This rating reflects the strength of the carabiner when it is closed and under load, ensuring that it can safely support the weight of a climber or equipment without failure.

The design and materials of a standard carabiner are engineered to withstand significant loads while also remaining lightweight and easy to use. Having a rating of 11,000 pounds provides a critical safety margin, allowing for dynamic forces that might occur during climbing, such as a fall or sudden movement, which can exert more pressure than just the weight of the load itself.

Higher ratings, like those listed in the other choices, are typically found in specialized or heavy-duty carabiners, but 11,000 pounds is the common standard for general use, making it essential for users to understand this when selecting equipment for climbing and rigging tasks.
