Mountain Gear says:
The Spirit Screw-Lock Locking Carabiner from Petzl is based on the legendary Spirit carabiner and uses Petzl's manual screw-lock locking system. This carabiner is designed for specific applications, for example for use at belay stations, or building anchors. It is very compact, and has an H cross section to reduce weight, as well as the Keylock system to avoid the carabiner snagging during maneuvers.
Historic Range: $15.95
