Petzl Freino Carabiner + Friction Spur Olive/Red, One Size

The Petzl Freino Carabiner is a unique locker with a friction spur that adds or adjusts braking power during single-rope descents, and it can also assist belayers with lowering climbing partners. You can use the locking carabiner with or without the friction spur, and it functions as a normal twist-locking carabiner. Once you've rigged your single-rope rappel, or your climber is ready to lower, you can easily loop the rope around the friction spur for better braking control.
