What are considered weak parts of a carabiner?

The weak parts of a carabiner are typically regarded as the nose, pin, and gate. The nose, which is the part that secures the gate when closed, is susceptible to wear and damage over time, especially in situations where the carabiner might be subjected to abrasive surfaces or repeated impacts. The pin is also a crucial component that holds the gate in place; if it becomes bent or damaged, the integrity of the carabiner can be compromised. The gate itself is critical for the carabiner’s function, and if it does not secure properly or becomes damaged, the carabiner may not serve its intended purpose safely. Therefore, these components are the weak links in the design and functionality of a carabiner, and it’s essential for users to be aware of their condition to ensure safe operation in rescue scenarios.
