Petzl Locking Carabiner - Brand: Petzl - Type: Locking Carabiner - Color: Silver/Orange - Use: Mountaineering/Climbing Thank you for viewing. I've decided I no longer need this due to a system review. I'm selling it because I have more climbing gear and fewer opportunities to use it. It's large, but you can secure it in one go, so I used it especially for self-belaying. I'm organizing my gear. I have other items for sale as well. Please consider them together. Suitable for via ferrata lanyards.
