This belay locking carabiner from Black Diamond features a unique gate design that prevents the carabiner from rotating in the harness's belay loop, enhancing safety. * BD's unique gate prevents rotation during belaying. * Hot forging is employed. * The I-beam spine design ensures a large contact area with the rope. Weight: 76g Strength: Closed gate = 22kN, Open gate = 8kN, Minor axis = 7kN Gate opening: 21mm * Purchased new in June 2018. * The COVID-19 pandemic began a year after purchase, and I drifted away from climbing due to age and physical condition, so I'm selling it. I hope someone else can make good use of it. * Please understand that the color and texture may appear different depending on the photo. * Please consider this item as used. * I am also selling a Black Diamond ATC Pilot. I will accommodate "combined purchases." Thank you for looking.
