What is the rated strength of a large steel locking D carabiner?

The rated strength of a large steel locking D carabiner is more than 9,000 lb, which is a widely accepted standard in the climbing and rigging industries. Steel carabiners are designed to handle significant loads and are manufactured to meet specific strength ratings to ensure safety during use.

The higher strength rating of more than 9,000 lb is particularly important for heavy-duty applications, where the carabiner may be subjected to substantial force. This strength is achieved through the use of high-quality steel and engineering designs that provide durability and reliability. In contrast, the other options reflect lower strength ratings which do not apply to large steel locking D carabiners, emphasizing the importance of choosing the appropriate gear for specific weight requirements in safety-critical situations.
