The Petzl William Screw-Lock Carabiner is a large, pear-shaped locking carabiner designed for belay stations and belaying with a Munter hitch. Its ergonomic design and Keylock system facilitate easy handling, even when wearing gloves. The carabiner features a manual screw-lock mechanism with a red band indicator, providing a visual warning when the carabiner is unlocked. It is constructed from lightweight aluminum, reducing the overall weight of climbing equipment. The pear shape offers a large capacity and wide opening, making it suitable for connecting multiple items and allowing for the creation of a Munter hitch in case of retreat. The fluid interior design limits the risk of snagging and facilitates rotation, while the Keylock system prevents involuntary snagging. The H-shaped cross-section ensures an improved strength-to-weight ratio and protects markings from abrasion. The carabiner is certified to CE EN 12275, UIAA, CE EN 362, EAC, NFPA 2500 Technical Use, XF 494: FZL-G-Q, and GB/T 23469/B standards.
