    RockLock Twistlock Carabiner

    Black Diamond's RockLock Twistlock Carabiner automatically locks after you set the belay for your climbing partner. That means no more looking down and noticing an unlocked gate after you told your partner to climb on. Black Diamond also designed this locker with a keylock nose for snag-free unclipping, a curved spine for a larger gate opening, and a square hinge to hold your belay device in place.

    • Black Diamond's biggest locking carabiner outfitted with a twistlock
    • Twistlock automatically locks gate and twists to unlock
    • Keylock nose eliminates snagging when unclipping

    Good, but crossloads very frequently

    • Familiarity: I've put it through the wringer

    The edge of the gate will get caught on the belay loop. There's no record of any biner actually breaking under belay use, crossloaded or not, so this may be theoretical, but it can startle both belayer and climber if the biner suddenly rotates to the major axis loading when loaded. If you don't care about that, this is a reliable autolocker with an easy gate action. I had to lubricate it to prevent squeaking and stop it from occasionally catching at the 90% rotation point, after that it's been buttery smooth. It seems to wear well and is beefy.

    Yes, I have experienced the same cross loading issue.

    Choice for Ice

    • Familiarity: I've put it through the wringer

    Trusted brand. Love these for ice. Faster than a screwgate, and doesn't freeze up as often.

    BD stuff rocks as usual

    • Familiarity: I've put it through the wringer

    I own many different brands of lockers and have found these to be consistently as reliable as the best of any other. Can't bring myself to use a screwgate though no matter who makes it.

    my favorite

      this is my favorite locking carabiner.


        high quality, built to last, operates smoothly. i will buy more.

        my go-to

        • Familiarity: I've put it through the wringer

        I'm a huge fan of twistlock carabiners, especially for belaying and going in direct with my PAS. I have 3 of these now, and they're my go-to every time. The two-stage locking mechanism is really intuitive (I personally hate three-stage lockers with a passion). If you're not opposed to a twistlock, this is the perfect one to get multiples of.

        Easy To Cross Load When Belaying

        • Familiarity: I've put it through the wringer

        This is a great all around auto locking carabiner; however, it has a tendency to move around and cross load when belaying with an ATC.

        Great Biner!

        • Familiarity: I've put it through the wringer

        Love the twistlock feature. Very easy to use once you get used to it. I use this indoors and outdoors as my primary locking biner for belay. I always double check that it is locked, but haven't had an instance where it wasn't yet. Another great BD product!

        Great twist lock

          I use this biner at the gym for belaying. It's great that it's always locked for safety.

          Need it

          • Familiarity: I've used it several times

          I have no need for any other carabiner anymore. This is my go-to.


            I use this guy for everything and the twist-lock is great when you get used to it

            Good. Still not exactly what I need

              The item is well constructed and strong. It has a "twist lock" which is good for better security.
              However the item is rather big and bulky for what I intended to use it for.
              I just wanted the gate opening to be 1" so that I can put it on my bike handlebar to hang a whistle and a small wrench .You'd be surprised how hard it is to find a carabiner that has a gate opening of 1 inch. They are either too big or too small, even those "S-shaped" carabiners. They are expensive too. This one was of a good price considering from other stores. However though I think this is a well made item, I will probably return it. I need something of a more conpact design and I feel that the price I paid for it, as comparatively affordable as it was, is too much for the simpler design that I need.


              • Familiarity: I've used it several times

              First caribiner and im diggin the simplicity of the twist lock. makes switching from climbing to belaying in the gym much faster

              Love the TwistLock

              • Familiarity: I've put it through the wringer

              BD nails it again with this sleek, easy to use TwistLock carabiner. If you're debating between a screwgate and a twistlock gate, I strongly suggest the twistlock. It's so easy and is really safe - it takes a bit of effort to actually twist it, so it's not something that you can mess up while belaying (those were my beginning climbing partners initial concerns).

              I highly recommend.

              Great biner!

                The Black Diamond Rocklock Twistlock automatically locks which provides great piece of mind when belaying or rappelling. As with other BD climbing products, it's solid and ready for daily (ab)use.

                Favorite Belay / Rap Biner

                • Familiarity: I've put it through the wringer

                I swear by the RockLock Twistlock biners for belaying and rappelling. They're a great size, and very intuitive to unlock and open with one hand (after a little practice).

                Black Diamond Rocklock Twistlock

                • Familiarity: I've put it through the wringer

                The automatic locking system is a pretty sweet feature, helps get in and out of your carabiner that much easier. You should always check to make sure its locked but for me it provides much more comfort knowing that it will automatically lock. I use this product indoors and outdoors a minimum of 3 times a week and I love it! I highly recommend.

                My favorite twistlock 'biner.

                • Familiarity: I've put it through the wringer

                I don't even mess around with other brands or models of twistlock carabiners anymore. The locking feature on this is silky smooth and substantial, and it's wonderful to have (mostly*) clip-and-go security when you use these for personal anchor systems and belay devices (*I say "mostly" because you ought to always check and double check that your carabiners are locked when belaying, rappelling, or setting up a personal anchor system, but the immediate locking feature of the twistlock offers some peace of mind!).
