Using the power of magnets to reinvent the auto-locking carabiner, the patented Magnetron RockLock combines maximum security with ease-of-use like never before. 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.

  • I nnovative 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
  • Easy operation with either hand
  • Square hinge end holds belay loop securely in place
  • Slightly curved spine maximizes gate opening
  • Type H or HMS connector. For dynamic belaying using a Munter Hitch or belay device.

RockLock Magnetron Carabiner is rated 4.6 out of 5 by 17.
Rated 5 out of 5 by from Smooth, Easy-to-Use, and Secure Locking Carabiner! This carabiner, unlike other types of locking carabiners, is much easier to use and gives the same, if not better, peace of mind when being used. I use it when belaying and it is a rock solid locking carabiner - easy to check the lock and easy to unlock, yet secure. I ordered several more of these to have in my gear stash because they are such a dream to use. They are smooth all the way around the inside, and nothing gets hung up, in contrast to the screw-lock and twist-lock/auto-lock rings of other locking carabiners, which provide ample opportunity for the rope to get hung up on and twisted. This carabiner is smooth, easy, and puts my mind at ease.

Rated 3 out of 5 by from Solid Carabiner - Except in Snow I used a couple Magnetron Carabiners throughout the summer for multi-pitch trad/sport routes and basic mountaineering. Found them light and easy to manipulate. Winter has come to the mountains, and I find that these lock up when they freeze or pack with snow. To free them up takes a lot of effort; a whole lot more than with a traditional auto-lock - especially with gloves on. Just a Heads Up. Keep it from Freezing and it's a great carabiner. Kudos to Black Diamond for the inovative approach.

Rated 4 out of 5 by from Good Have used the vapor lock before, switched over to the rocklock because of higher working load.. smooth and easy to use.. if using on construction site, or anywhere with metal shavings from drilling, grinding, welding, etc. the gate can become clogged, difficult to clean and not lock

Rated 4 out of 5 by from What to lube with? Hey guys, been using this for a long time now since it came out -- the gate almost never closes properly by itself anymore, have to push it the last 10% of the way to lock it. I am assuming it needs to be lubricated but the instructions don't say what type of lube is appropriate?

Rated 5 out of 5 by from Beautiful, simple, easy to use and secure Here's some thoughts; - Normal screw locking gates can get stuck - These don't - these are very light weight - these are BIG...but not too big. It's like the 3 bears story, eh. - One hand pinching, on and off. Super easy - I like the big opening to allow to several ropes and slings fit in. I don't do it often but when I need works now. - It is so clean and beautiful

Rated 5 out of 5 by from Love it! Makes clipping in so easy. Got this over a year ago and have fallen in love with it. The double ping release makes it very easy to unlock and clip in. Checking the lock is simple. Bought the same one for my girlfriend! We both love it. Really durable as well. Won’t need another one for years to come.

Rated 5 out of 5 by from The Magnetron RockLock My typical go-to big lockers are the regular RockLocks and I really just got these to try out something new. I've had friends give me good and bad comments about any magnetron, but I will say that I am a fan. Climbing here in Colorado I've had no problem with dust and I find these just fine for use in my anchors. Not only that but I love to use them in the gym when teaching.

Rated 5 out of 5 by from Amazing Carabiner This carabiner is both easy to use and to check for safety. The pinch feature has just as much flow as your favorite route, all while removing any edges or locks for the rope to hang up on. Even if 1 of the 2 locking magnets isn't engaged there is no way to open the gate, which gives me an added feeling of security. Love it.
