Thank you for viewing. Petzl SM'D Wall Carabiner Set of 2 Decided to sell due to system review. My climbing gear has increased, and I have fewer opportunities to go, so I'm offering these for sale. A small hole allows you to thread a cord to prevent items like a tie block from falling. I'm currently organizing my gear. Please consider purchasing.
