Petzl - OK Ball lock

The Petzl OK Oval Carabiner (BALL-LOCK) is a symmetrical locking carabiner designed for optimal alignment with pulleys, ascenders, and rope devices. It is suited for climbers and technicians who need clean, stable connections in pulley and rope systems. What this solves Standard carabiners can misalign devices, leading to inefficient loading and unstable setups. How this solves it The oval shape keeps devices centered, ensuring: optimal load distribution smooth rotation of attached tools stable system alignment Why this tool Unlike asymmetric carabiners, this is built for device compatibility: oval shape → ideal for pulleys and ascenders BALL-LOCK → fast, secure operation smooth interior → reduces snagging and friction It is designed for clean, efficient mechanical systems. Best for Beginner / Advanced / Expert — for pulley systems, ascenders, and technical rope setups. Key features Symmetrical oval shape for optimal alignment BALL-LOCK automatic locking system Smooth interior to reduce snagging Keylock nose Lightweight H-frame construction Used with Pulleys Ascenders Progress-capture devices Rope systems What’s in the box 1× Petzl OK Oval Carabiner (BALL-LOCK) Dimensions / Specs Weight: ~75 g Gate opening: 23 mm Major axis strength: 25 kN Minor axis strength: 8 kN Open gate strength: 7 kN Material: Aluminum
