Which option is an auto-locking carabiner design?

• A. Auto locking carabiners (twist collar and pull gate)
• B. Screw gate carabiners
• C. Supersafe carabiners (push up, twist collar, pull gate)
• D. Industrial clips (snap hooks)

Answer: (A)

Auto-locking carabiners are designed so the lock engages automatically when the gate closes, reducing the chance of it opening by accident. The twist collar with pull gate is a classic auto-locking design: you unlock by twisting the collar, but once you release the gate, it automatically re-locks, keeping the connection secure without an extra step. In contrast, a screw gate requires you to manually twist the sleeve to lock, so it isn’t auto-locking. The other option described with a push action plus twist collar and pull gate involves a deliberate unlock step, so it isn’t automatically locking by default. Industrial clips aren’t carabiners at all and don’t provide the same locking mechanism.
