What is a carabiner?

A carabiner is defined as a metal load-bearing connector used in climbing, rescue, and other applications where securing and connecting equipment is crucial. This device typically features a spring-loaded gate that allows for easy attachment or detachment from climbing gear, ropes, or anchor systems. The strength and reliability of a carabiner make it an essential component in maintaining safety during high-angle rescue operations and climbing endeavors.

While harnesses, methods of ascent, and knots are all important elements in climbing and rescue contexts, they do not accurately describe what a carabiner is. Harnesses secure the climber or rescuer at a point of connection, methods of ascent refer to the techniques used to climb, and knots are used for securing or joining rope ends. Each of these serves a distinct purpose, but none of them embody the specific characteristics or function of a carabiner as a load-bearing connector.
