    Unlike anything else.

    The Black Diamond Magnetron RockLock carabiner uses a truly revolutionary gate that locks shut with magnetic tabs instead of a traditional screw gate. The advantages? Nothing to freeze shut in the winter or to clog up with sand, and you can operate the gate with one hand. Not to mention that this gate is significantly faster to open then traditional locking mechanisms. To top it all off, Black Diamond gave the RockLock carabiner a keylock nose that won't snag on gear, slings, or bolts when you tear down your anchor to head up the next pitch. Note: the locking mechanism comes in different colors (dark blue, light blue, green, or orange), so you might not get the blue that's pictured.

    • Revolutionary magnetic locking gate features two magnetized arms that repel each other when the gate is open but lock shut when they come in contact with the steel insert in the carabiner's nose
    • Gate opens by depressing the two arms with thumb and forefinger; can be operated with one hand, and design works equally well for right- and left-handers
    • Slightly curved spine maximizes gate opening
    • Magnetic gate doesn't have components that can freeze shut or clog with sand
    • Keylock nose helps prevent your rope from snagging
    • Hot-forged for maximum durability
    • Note: locking mechanism comes in different colors on the carabiner, so you might not get the blue that is pictured

    Solid Choice

    • Familiarity:I've put it through the wringer

    I used this biner belaying for a ropes course all summer. It makes clipping in and out of an ATC effortless. The Rock lock is a big big biner that lets the rope glide effortlessly. (You will see the anodized finish wear off though) Hundreds of belays and it never froze or stuck.

    • Familiarity:I've used it several times

    I love this carabiner for winter mountaineering. The magnetic gate is easy to use while wearing gloves, much easier than earlier designs of push and twist gates.

    Otherwise functions like a carabiner should!

    Good for Climbing, bad with obstructions

    • Familiarity:I've put it through the wringer

    The concept of the auto-locking mechanism using magnets is a stroke of genius. Super simple and great for one-handed operation. I used it on the end of my rescue sling during swiftwater rescue this summer . My one gripe with this carabiner is the way the mechanism is set up the slightest bit of sand and the gate won't open, not the best for rescue situations. I've also had reports of people using it when ice climbing and a similar problem occurring. Great for a belay biner but I'd discourage any situation where the biner would be on the floor making it more susceptible to having the mechanism be clogged.

    Nice 'Biner; Bit Expensive

    • Familiarity:I've put it through the wringer

    Works well, simple to use. After a couple uses it becomes more natural to open and close, and it now feels like I am using a non-locking carabiner. The coating on the metal wears off after awhile of having rope rub on it, and it would have some sharp parts rounded off and smoothed out a little more by the locking mechanism. Overall nice product.

    (Only used this indoors so far, no idea about outdoor performance.)

    Good for certain situations

    • Familiarity:I've put it through the wringer

    All around a good carabiner. Not much I can say that I don't like about it. I have used many different types of carabiners, some good and some horrible and I would say this one is at the top. No problem with cross loading while belaying or anything like that. Once again BD didn't disappoint.
