Petzl Rockin Carabiner Used for about 2 years at the gym. There are scratches on the areas where the rope rubs. See photos 4-5. Please understand that this is a used item before purchasing. I also sell other items necessary for belaying. If you buy multiple items, I will offer a discount, so please contact me. Product Details Carabiner with anti-reversal function using a "bar". The "bar" prevents the gate from closing unless it is completely locked, reducing the risk of misuse. If the "bar" is set in the closed position, the lock will not accidentally release. To prevent switching, returns are not accepted. Thank you for your understanding.
