Petzl William Screw Lock Carabiner


The large-capacity Petzl William carabiner has been designed to easily connect multiple items. The asymmetrical pear-shaped design provides a wide opening, helping to prevent snagging and allowing plenty of room to create a Munter hitch if needed.

As with other Petzl carabiners, the William is compatible with the Captiv bar, a simple piece of equipment that keeps the carabiner oriented to keep load distributed across its major axis, improving safety and ease of use.
