Locking carabiner

A locking carabiner is a type of carabiner used in lead climbing and sports climbing that includes a secure mechanism to prevent accidental gate opening. This mechanism can be a screw-gate, auto-locking, or twist-lock system. Locking carabiners are often used at critical points such as securing the belay device, attaching to anchors, or connecting critical safety systems, providing an extra layer of security compared to non-locking carabiners.

Examples

In lead climbing and sports climbing, a locking carabiner is essential for safety. It is used to secure the climber's belay device to the harness. This type of carabiner has a mechanism that locks the gate, ensuring it won't accidentally open during a climb. Climbers commonly use it to attach themselves to anchor points or for critical gear placements, minimizing the risk of accidental disengagement.
