The Petzl WILLIAM series of carabiners are all about facilitating smooth interactions with wider load attachments, such as those created by webbing, slings or side by side D rings. Hitch aficionados will also find the WILLIAM well suited for work with the munter, clove and other friction hitches. This carabiner is available in two color variations, regular and tactical. The regular color scheme features screw-lock, ball-lock and 3 stage auto-locking gate options, while the tactical variant offers screw-lock and 3 stage auto-lock versions. A keylock design in the nose of the carabiner helps prevent snagging.
