What kind of carabiners are used on the arms of the lobster claws?

• A. 2 screwgates
• B. Steel auto-locking
• C. Auto-locking or the industrial clips
• D. Supersafe

Answer: (C)

The key idea is using locking carabiners for a secure, reliable connection. The arms of the lobster claws handle dynamic loads and movement, so you want a gate that won’t open by accident. Auto-locking carabiners have a gate that automatically locks after clipping, and industrial clips are built for rugged, high-load use with strong locking mechanisms. These ensure the connection stays closed even when the gear bumps, twists, or is handled in tight spaces. Non-locking or simple screwgate types can loosen or open unintentionally, which isn’t safe in this context. So auto-locking or industrial clips provide the necessary security and durability for that application.
