What kind of carabiners are used at participant hookups?

• A. 2 screwgates
• B. Auto-locking
• C. 2 autolocking
• D. 2 screwgates or a supersafe

Answer: (D)

At participant hookups, the safety focus is on keeping the connection securely closed and not easily coming undone during movement. Locking carabiners are used so the gate can’t accidentally open, which is crucial when a rider is attached and shifting around.

Using two locking carabiners provides redundancy and allows you to visually confirm both gates are locked before connecting, dramatically reducing the chance of an unexpected release. The option of using a Supersafe, a locking carabiner designed for secure hookup work, offers a reliable single-unit alternative when appropriate. This combination—either two screwgate carabiners or one robust locking carabiner like the Supersafe—meets the requirement for a secure, lockable connection at the hookups.
