Rocklock Screwgate Carabiner | Black Diamond

Canada's Source for Locking Carabiners

Secure Handling for Belay and Rappel

The Black Diamond RockLock Screwgate Carabiner is the largest locker in BD’s lineup, built for belaying, rappelling, and anchor systems. Its hot-forged construction and redesigned spine improve handling and reduce weight without compromising strength.

Reliable Locking and Compatibility

Featuring a keylock nose and Munter Hitch compatibility, the RockLock can be operated with one hand for efficient rope work. The square hinge end keeps the belay loop securely in place, enhancing safety during dynamic belays.

Durable and Eco-Conscious Build

Made from 7075 aluminum with 25% pre-consumer recycled content, the RockLock reflects Black Diamond’s commitment to sustainability. Its larger rope-bearing surface increases durability and reduces rope wear over time.
