Petzl William Screw-Lock

The William is a large, lightweight carabiner for use in rope systems. Its pear shape allows the connection of multiple items, and works well with a Munter hitch. The keylock nose and fluid interior reduce snagging and encourage major axis loading. The William's H cross section protects marking from abrasion for the life of the carabiner. The William is available in a Screw-Lock, Ball-Lock, and Triact-Lock mechanism - this is the Screw-Lock mechanism.
