The Petzl William Screw-Lock carabiner is a large, pear-shaped aluminium locker that gives you plenty of space and control at the belay and when using a Munter hitch. Its wide gate opening lets you clip several pieces of gear cleanly, while the HMS shape makes belaying and tying a Munter smooth and predictable, even when your harness is already loaded with equipment.
The ergonomic asymmetrical shape is easy to handle with gloves, the screw gate is quick to operate, and the Keylock nose prevents snagging on slings or anchor rings. The manual Screw-Lock system is particularly well suited to occasional opening and closing or dirty environments where an automatic lock could clog – ideal if you want a robust, dependable main belay carabiner that gives you calm, controlled handling on every stance.
