Petzl William Ball Lock Carabiner

The Petzl William Ball Lock carabiner is a large, pear-shaped aluminium locking carabiner designed to give you plenty of space and control at the belay and when using a Munter hitch. Its generous gate opening lets you clip several elements cleanly, while the HMS shape makes belaying and tying a Munter smooth and predictable, even when your harness is already crowded with gear.

The ergonomic shape is easy to handle with gloves, and the Keylock nose prevents snagging on slings or anchor rings. In the Ball-Lock version the carabiner locks automatically and offers triple-action security, giving you an extra margin of safety without slowing you down during frequent opening and closing – ideal when you want maximum reliability at belays, in rope systems and in rescue situations.
