Participant hookup carabiners are described as?

• A. Two screw gate carabiners or a super safe
• B. Two auto locking carabiners
• C. Non-locking carabiners
• D. Aluminum lobster claws

Answer: (A)

Two locking carabiners, with the option of screw-gate types or a locking “super safe” style, are used for participant hookup. The idea is to connect the participant securely to the safety system with hardware that stays closed during use. Screw-gate carabiners require a deliberate twist to open, which helps prevent accidental unclipping, and a “super safe” auto-locking design locks automatically after closing for extra security. Using two of these provides redundancy: if one connection moves or needs adjusting, the other still keeps the participant attached. Non-locking carabiners can unclip under load or vibration, so they aren’t suitable for hookup, and aluminum lobster claws aren’t the standard secure connectors used in professional challenge courses.
