Our large, versatile locking biner featuring Magnetron Technology, which uses magnets in the gate and a steel insert in the nose for unprecedented security and ease of use. Learn More


Combining maximum security and ease of use like never before, the Black Diamond Magnetron Rocklock uses the power of magnets to reinvent the auto-locking carabiner. Magnetron Technology uses two magnetic arms in the gate and a steel insert in the carabiner's keylock nose to create an ultra-secure, self-clearing and redundant locking mechanism that can easily be used with either hand. Our classic RockLock shape is ideal for belaying, making anchors or rappelling, and its keylock nose prevents snagging on slings and ropes.

  • Innovative gate design uses two magnetic arms in the gate and a steel insert in the nose for super-secure, interference-free closure
  • Keylock nose prevents snagging
  • One-hand operable
  • Square hinge end helps hold belay loop securely in place
  • Slightly curved spine maximizes gate opening
Hot Forging vs. Cold Forging


We use two different forging methods to build carabiners—hot and cold forging. Each has its benefits and using both allows us to achieve the best possible shape, size and strength for each carabiner’s intended use. HOT FORGING, a process where both the rod stock and forge dies are heated, allows us to “move” the metal, creating more intricate shapes, such as our GridLock and Oz biners.

    Rated 5 out of 5 by Very convenient. Time saver. No fumbling with gates. Very easy to use. Quickly opens and closes, letting you focus on your climb and partners. January 11, 2016
    Rated 5 out of 5 by Brilliant I love this crab it is so simple to use and it's a smart design I will be getting more of these, it's definitely worth the price. December 24, 2015
    Rated 5 out of 5 by Safest locking carabiner I've ever used Because the default position of this carabiner is closed and locked, there is almost no way to assume it's locked when it isn't. This is especially nice when tired and/or in the dark. Also it may be easily opened with either hand. It is the first locking carabiner I've used in the 50+ years I've been climbing that seems idiot-proof. November 14, 2015
    Rated 5 out of 5 by Big improvement over twist lock carabiners I have used twist lock carabiners for years, and screw locks before that. The magnetic locks are great. Easy to open one handed; closes and locks automatically when you let go. It is also a good size; not too big, not too small. Until something better comes along, I will be using this for my rappel/belay needs. September 2, 2015
    Rated 5 out of 5 by Perfect for Rock This is one of the easiest to use locking carabiners on the market right now. It is as easy to open as any non locking carabiner, but just as safe if not safer than any locking carabiner. I have tried every way I can think of to bust it open with no luck. I admit that I was very skeptical at first and wanted to test it myself. The only application I wouldn't recommend it for is in winter with heavy gloves, it is hard to release. If you just have a light pair no problem though. May 21, 2015
    Rated 5 out of 5 by Awesome Carabiner!!!! So simple and smooth to use! Hasn't locked up at all. I hesitated to switch from the screw gate to this but after I did I was blown away! You don't have to worry about anything getting caught and you don't need to worry about the carabiner opening by accident. Way to go Black Diamond! June 18, 2014
    Rated 5 out of 5 by Awesome high-functioning Carabiner!! I love this carabiner!! It works very smoothly and does not stick at all. It closes and opens easily but have NOT had it accidently open. This is my new favorite carabiner!! May 19, 2014
    Rated 5 out of 5 by I love it easy operation I love it the magnetic clip is so nice .I can easily slide it open with one hand with no problem .I can't wait to use it next season. May 11, 2014
