    The most revolutionary belay carabiner in a decade.

    Featuring Black Diamond's new magnetic locking mechanism, the Magnetron GridLock carabiner brings a new level of ease and safety to belay-specific carabiners. This unique gate design doesn't freeze in the winter and doesn't clog up with sand and dirt the way a screwgate does. In addition to the one-of-a-kind gate, the Magnetron GridLock also has a separated bottom and top so as to completely eliminate the chances of cross-loading, because this is one piece of gear that absolutely cannot fail. To further ensure that its safety, Black Diamond hot-forged this carabiner to make it as tough as it can be. As a final touch, this carabiner also got a keylock nose to eliminate snags when you're taking your friend off belay.

    • 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
    • Gate bisects carabiner to eliminate cross loading
    • Magnetic gate doesn't have components that can freeze shut or clog with sand
    • Large pear shape allows for a generous gate opening
    • Keylock nose helps prevent your rope from snagging
    • Hot-forged for maximum durability
    • Item #BLD3367

    Gets the job done

    • Familiarity:I've used it several times

    I've used this several times for belaying with a gri-gri and am personally not a fan. It's very helpful to prevent cross loading, but i usually maintain control with my guide hand to prevent that from happening anyways. I find that it just takes that much longer to get the gri-gri off the binger to load and unload the rope. It feels less efficient for me which, in rock climbing, is blasphemy. I grabbed it for my TR solo set up so i have a carabiner that won't cross load while I'm climbing, especially because its a little more dangerous if used for that type of climbing. Overall, it gets the job done, and really comes down to personal preference for your carabiners.

    Great for belays and rapels

    • Familiarity:I've used it several times

    I really enjoy the Magnetron technology, it's a very convenient locking mechanism. Simply squeeze and pull. The design of this can be a little frustrating when setting up, but once everything is in place the carabiner is great to work with. You do not have to worry about cross loading the gate while belaying because of the gridlock design. I've enjoyed having this carabiner and will continue to use it because of the easy gate.

    Gridlock + Magnetron = Way too finicky

    • Familiarity:I've put it through the wringer

    The original Gridlock is all right. Kind of solves a problem that barely needs a solution, and only a bit more trouble to deal with when transitioning from belaying to hanging off of your harness. You need to go through a few extra gate-opening steps to get the biner off your loop and the belay device in the bottom part of it, for hanging from your harness. Not much of a problem since for half of them you can just pull the belay device keeper loop down through the extra gate, and the open screwgate up top will swing open to let the device pass to the bottom of the biner.

    But when you have a Magnetron gate, those steps are a HUGE hassle. Opening the gate 2 or 3 times while maneuvering around the biner and belay device is so much more trouble when you need to hit the buttons every time. It's incredibly frustrating and probably increases the chance of dropping the biner or device. I would not recommend this product to anyone.

    Rush hour gridlock

    • Familiarity:I've put it through the wringer

    As others have mentioned it does take a little longer to attach to your harness and get set up than other carabiners. Once you get the process down it is only a couple seconds more. Eliminating the worry of cross loading your biner makes it worth it for me. Also the magnetic locking feature is basically magic. It automatically locks when the gate closes. How cool is that? I'll tell you, really cool.

    Good for long belays

      This is a great carabiner for long belays. It keeps your belay device in place and your carabiner from twisting on your loop. However it can be a pain to take on and off, so if are doing short routes and switching off often with your partner often (like in the gym) it becomes a nuisance.

      Getting used to the whole thing

      • Familiarity:I've used it once or twice and have initial impressions

      I just bought this for climbing and ski mountaineering. I am still getting used to the whole concept. I think I agree with Mike below that things get a little complicated with both of the concepts together and that I could be just as happy with the GridLock in a screwgate version.



      Nonetheless, this still does the job!

      Screwgate version is better

      • Familiarity:I've used it several times

      I love the magnetron gate and I love the gridlock, but I don't love them together. If you want a magnetron gate I'd get it on the RockLock. If you want a GridLock to avoid crossloading I'd get the screwgate version.



      The screwgate gridlock isn't hard to take on and off. The trick is you clip it to your belay loop, then you give it a little tug to pull the belay loop pass the crossload-prevention piece and into place. This briefly opens the gate as the belay loop pushes past the lil nib piece, therefore you can only do this when the gate is unlocked. Hence the problem with the magnetron gate: it's locked whenever the gate is shut and you can't just tug on it to get the belay loop into place. It's possible to hold the gate open during the whole belay setup, but it's not easy and I'd be really afraid of dropping my device in the process.

      Don't cross-load a Grigri

      Love the GridLock and Grigri combo! But be careful to orient the GridLock correctly. From the BD website: http://demandware.edgesuite.net/aakn_prd/on/demandware.static/Sites-BlackDiamond-Site/Sites-bdel/default/v1374818747544/files/M10137_C_LockingBiner_IS_WEB.pdf

      Don't cross-load a Grigri

      Perfect for Canyoneering, but sand sucks

        I have been using this for canyoneering since November 2012 and I haven't had any problems with it till June 2013 when the rope would get wet then sandy in the Zion canyons. While rappelling your carabiner and ATC help clean off the sand from the rope but some sand ends up getting under push tabs of the Magnetron and make it so it freezes up and stays locked. You have to really play with it to loosen up the sand if you don't have water to wash it out with which sucks since this biner is not supposed to freeze up with sand. I haven't had any problems with it not locking though so that is good.



        Overall I highly recommend the Magnetron to canyoneers, but if you are in super sandy conditions and using an older rope that holds sand well, beware of it freezing up just like any other locking biner.

        Cool Gate

        • Familiarity:I've put it through the wringer

        The gate on the magnetron has the magnets in the gate and when it closes it locks into groves. It can be opened with your finger and thumb just fine.If I did it all again I thing I would get the rocklock version. The gate locks every single time you close it because of the magnets, so it can get annoying to open it to put you gear in, close it to slide the gear down, and then open the gate again to move the gear to the bottom to prevent cross loading. Seems to be quality materials though! I have not had any durability issues.

        Cool Gate

        Great Design

        • Familiarity:I've used it several times

        Simple, easy to use, secure, everything that a belaying carabiner should be. Excellent work, BD!



        *Also* The colors of the magnetic arms for the Platinum color style carabiner can vary,as shown in previous review photos (mine came with blue arms, but I've also seen green and orange)

        Great Design
