    • A belay device great for new climbers
    • Aluminum material is light and sturdy
    • Offset D carabiner optimizes loading and ergonomics
    • Keylock nose won’t snag
    • Strategic shape resists flipping orientations
    • I-Beam construction is light yet super strong
    • Item #DMM0054

    My go to

    • Familiarity: I've put it through the wringer

    This was the first biner i bought for belaying and it has remained my favourite. It's real easy to tell when you have locked the screw gate. The only mishaps i've had with it is when i lend it to someone who doesn't know how to use it and they snap the plastic guard on the unlocked screw gate >:(

    The only lockers I use for belay!

    • Familiarity: I've put it through the wringer

    These are fantastic belay lockers! I love the security of having the belay device secured in a non-cross loading position. Not to mention, the self check system the black clip provides! Very easy for partner confirmation as well. Great locker.


    • Familiarity: I've put it through the wringer

    This biner has been the best i've owned! i love it. When i climb inside or out i always know that my biner will be locked whether it's someone new or me belaying! forces you to put it on correctly and have a double case for having it locked!!

    Great Belay Biner

    • Familiarity: I've put it through the wringer

    I have used this for a couple months now and it is a great biner. Keeps you from side-loading and makes you double-check that you're locked in. A no-brainer, especially for newer climbers who don't have the muscle memory down. Also, the biner seems to hold up well to fast belays/rappels. It should last a while.

    The best belay biner there is.

      Ohh the internal debate - 4 stars or 5 stars???? Let me make it clear I absolutely love this biner. I love the fact that you cannot cross load it, I love the fact that the plastic clip won't shut unless the screwgate is done up, I love its simplicity and I love the smoothest action you can find on any screwgate commercially made. (DMM do make amazing screwgates - FACT!!)

      So why 4 stars? The only reason I gave it four stars is because the plastic clip can be detached from the biner and lost. Over the last three or so years that I've been using mine only once has the plastic clip been twisted off the biner when I had it attached to one of my gear loops (maybe I should learn to always clip it fully closed but when I'm not belaying I sometimes leave it simply closed on a gear loop). Luckily, at the time it fell, not only did I notice it had been knocked off but also it fell somewhere where I could pick it up and re-attach it, ie it didn't fall 200feet down a rock face. I have also heard about one guy who had his plastic clip nicked in Camp 4 - not good! I guess the reason DMM manufacture it like this is so that you can take the clip off and use it like a normal biner but I never need that, I have a bunch of Shadows for that. Also when you compare it to a Girdlock, you cant take the metal piece off that - there's no 'semi' dual use for that biner, so I would say you could make the plastic clip a more permanent feature.

      Like I said though - this is an awesome biner and I wouldn't trade mine in for any other (Gridlock or anything). I'm currently thinking about getting one (two?) more to use with a Silent Partner.

      Unanswered Question

      Has anyone used the Belay Master 2 for ice/alpine climbing? From the posted reviews, no one mentions using this biner with gloves on, so I'm not sure what its rating for ice would be. Any thoughts?
