The Petzl William Lock Carabiner's extra-large gate opening makes it an excellent choice for anchors, belaying, and any other time you need a massive locking carabiner. The William is indispensable for belaying directly from the anchor point with a Munter hitch on single or double rope. Petzl also gave this locking carabiner a large basket to accept multiple slings and 'biners at complex anchors. Have you ever been on a wall climb when this didn't happen'
