The Petzl William is a versatile karabiner designed for belaying, abseiling, anchoring multiple ropes or slings, and keeping belay stations organised. Its pear-shaped, asymmetrical design provides a wide opening and large capacity, making it ideal for connecting multiple items or creating a Munter hitch during retreat. Constructed from aluminium, the William is lightweight yet strong, reducing the load carried by workers at height or climbers. Its fluid interior design and Keylock system minimise snagging and make handling smooth and intuitive. The H-shaped cross-section ensures an excellent strength-to-weight ratio while protecting markings from abrasion.
The William is available in three locking options: automatic Triact-Lock, Ball-Lock, or manual Screw-Lock, providing flexibility to suit different safety and operational requirements. For additional stability, it can be used with the Captiv bar, keeping the karabiner oriented along its major axis to limit flipping and maintain proper integration with your system. Ideal for professional rope access, climbing, and rescue operations, the Petzl William karabiner combines safety, efficiency, and practicality in a single, reliable connector.
