Maximized size and security define the RockLock Triple Lock Carabiner
What Our Gearhead® Experts Are Saying:
"The RockLock Triple Lock is a staple on my harness. Its large size makes rigging and belaying so much easier, and I love that I can operate it with one hand. The triple-lock system adds peace of mind for high-stakes climbs."
When we need reliability for belaying and rappelling, we reach for the Black Diamond RockLock Triple Lock Carabiner. As Black Diamond's largest belay and rappel locker, the RockLock excels in usability and security. Its wide gate opening, enabled by a slightly curved spine, simplifies clipping while the square hinge end holds belay loops securely in place.
The keylock nose ensures snag-free performance for seamless transitions, and the triple-lock system provides an added layer of safety without sacrificing convenience. Whether we’re using a Munter Hitch or belay device, the RockLock’s versatility and one-handed operation make it a dependable choice for technical climbs and everyday belays alike.

Best Auto locking carabiner
Great single handed auto carabiner. These are so easy to use; great for belaying in an indoor setting. The product feels high quality and built to last.

Great for belay
I wanted a trustworthy and simple autolock solution for my belay device. The push-up and twist is the perfect amount of action to open the gate without any accidental opening.
