How to choose a carabiner
Locking carabiners can have either manual locking or auto-locking systems. Manual systems (SCREW-LOCK) require the user to screw the sleeve on the gate to lock it.
They are great for carabiners that are opened and closed only occasionally, like the central carabiner at a belay station. Manual systems are recommended for use in gritty environments, where dust and dirt could cause auto-locking mechanisms to malfunction.
With auto-locking systems (BALL-LOCK, TRIACT-LOCK, TWIST-LOCK) the gate locks automatically, an advantage for carabiners that are opened and closed frequently, like the carabiner that connects a belay/rappel device to a harness.

Petzl carabiners come in three main shapes, each one is designed for a specific purpose:
For connecting belay/rappel devices or for use at the end of a lanyard.
