The William’s large internal working area is perfect for use with a Munter hitch, even with thicker double ropes. At an anchor, you won’t be fumbling for space to clip into. The William’s heavy offset design also helps prevent cross-loading when belaying as it shifts into position. Like all Petzl biners, the William boasts the snag-free, strength-enhancing design keylock closure, and red “unlocked” warning indicator.
