What is the gate of a carabiner?

The gate of a carabiner refers to the opening side of the carabiner that allows it to be connected to a climbing system, anchor point, or another piece of gear. This is a critical feature for functionality because it provides access to the interior of the carabiner, enabling users to easily attach and detach the carabiner as needed during rope rescue operations or climbing activities. The design of the gate, whether it is spring-loaded, screw-locking, or a twist-lock mechanism, directly impacts the safety and security of the connection. Understanding the purpose of the gate helps users ensure proper usage and handling of the carabiner, which is vital for safety in any rescue or climbing scenario.
