    Sport, trad, or big wall—get up there with the DMM Shadow Carabiner.

    DMM's I-beam construction gives the Shadow Locking Carabiner a burly 24kN of strength. The Shadow comes with a standard screwgate, a speedy auto-locking quicklock gate, or a super secure locksafe gate. All Shadow carabiners have keylock noses to prevent snagging.

    The only locker I use anymore.

    • Familiarity: I've put it through the wringer

    my favorite locking carabiner. the gate is ultra smooth way better than any of black diamond screw gate locker My friends like them better then there petzl. The shape is just big enough for any sport or trad climbing need. An it’s ultralight wait make it perfect for alpine climbs. Ive replaces all my lockers with this one an if you buy it you’ll make the switch too.

    Does The Trick

    • Familiarity: I've used it several times

    A great option for a lightweight, good value locking carabiner. I use this and the DMM phantom whenever I'm in the gym - it's strong, durable, and I've never had problems with it staying locked. Great purchase.

    A Solid, Light D

    • Familiarity: I've used it several times

    Quick comparison of three lightweight lockers:
    DMM Shadow
    Petzl Spirit
    Mammut Wall Micro

    All are offset D's with similar strength, weight, and profile. They're 'normal' sized - smaller than BD's Vaporlock and larger than DMM's Phantom Screwgate. I've used the Spirit the most (along with the slightly smaller Edelrid Pure Screw), but I can easily see going with any one of them.

    Since personal preferences change with little things, here are the details: this has the widest frame at the top, with a more gentle angle than the Spirit, and firmest gate spring.

    BD's Positron is in this general group, too, though it's a tad heavier and stronger, with a slightly wider gate.

    How else to choose? Maybe from their multilingual pictogram instructions.
    • Clearest: Petzl. A few words go a long way.
    • Best rebus puzzle: BD. 'Check for signs of wear before clipping into a clothesline'?
    • Most amusing pictures: DMM. 'Never, ever use your carabiner to build a sandcastle.'

    Great lightweight lockers

    • Familiarity: I've used it several times

    I have appreciated the craftsmanship of other DMM products like their nuts. These locking carabiners are very light and as others have noted the locking mechanism is smooth.

    I picked up a few of these for use in anchors. It would be too small for my taste in use with a belay device. But, for ascenders, anchors, and other places you want a locking carabiner these would be great.

    Solid biner

    • Familiarity: I've put it through the wringer

    As mentioned before, this thing is noticeably lightweight compared to some of my older Petzl biners. I prefer the screwgate lock and love it.

    The Perfect Light Weight Carabiner

    • Familiarity: I've used it several times

    This is one of my favorite beeners because it's light weight, it looks cool, the locking is solid, and the price isn't bad. When you need light weight and versatile it's got you covered, the only thing I wouldn't suggest using this for is when you need your belay device to have a large range of motion because it is thinner on it's inside edge than most carabiners I've used. (I bought the screwgate, the auto-locking is probably the same though)

    Great Lightweight locker for multipitch

    • Familiarity: I've put it through the wringer

    This is a great lightweight biner for long routes, alpine routes and anywhere you want to keep the weight down. This is the qualify folks expect from DMM.


    • Familiarity: I've put it through the wringer

    Great Locking biner to use on an anchoring system. The movement of opening is ergonomical sound. Simple twist, don't have to fight it, and fits well in the hand. You need to physically try this biner to love it's functioning.

    The perfect lightweight locking biner!

    • Familiarity: I've put it through the wringer

    I bought this biner for using on my PAS for clipping myself to the chains. It is my favorite biner I have found yet for this purpose! It is incredibly lightweight, and is small enough that you can clip through any link on the chain. :) As always, DMM delivers a super smooth screwgate that glides more smoothly than any other carabiner I've tried. (P.S. Also, DMM products are made in Whales, not sweat shops, so you can feel good about buying their product).

    Ultralight and solid. With an issue

    • Familiarity: I've put it through the wringer

    Grab couple of these screw locks to trad or sport multi-pitch.

    I use one to clove hitch myself and another to belay my second off an anchor. I prefer something bigger (e.g. Petzl Attach 3D or Mad Rock Tech HMS) as a belay binner due to a high friction between my ropes and DMM Shadow.

    It's a solid ultralight binner with common ultralight binner issues - high friction and gets only one clove hitch. Also I wouldn't take it to alpine climb because it's too small to be handy when wearing gloves.

    Gate action and screw lock is very smooth (like any other DMM binner).

    For summer trad or sport multipitch climbs it's hard to get something better.

    Updated on Tue Apr, 9th 2013 after approx 1 year of use. This binner paints rope badly. Do not use it for TR setup.

    Well, if your rope is dirty, especially if it has picked up sand, it WILL wear out a carabiner. Since DMM biners are both anodized and hot forged, they are as tough as they get, so ignore that "binner paints rope badly" comment folks.

    5 Star ratings are over used IMHO

      ..but these bad boys truly deserve it. They really are a joy to use, the gate action is so smooth and the biner is so nice and light, but it also feels strong and reliable. I have owned a few of the screw gates for a few years now (they are my de-facto biner for anchors). I have only just ordered a locksafe one now so comment on that one but the screwgates at $13.90 are good value I would say, based on the quality of the product.

      If people are wondering what the difference is between the Zodiac and the Shadows, the Zodiac is slightly bigger, a bit heavier and a bit stronger (32Kn major axis versus 24Kn on the Shadows per Backcountry specs). The two are very similar and the size differential is not that noticeable, both are excellent and you can decide which one is more suitable for your own use but I think both of them are top of their game.


        While I own a good deal of BD biners, I have two DMM lockers, and the gate action always feels smoother than the BDs. Just an observation. Maybe it's all in my head. Regardless, BD and DMM both make awesome gear.

        I totally agree with you! While I admit to being a BD zealot for most of my gear, I have found DMM biners have a much better gate action. I switched out my locking biners last year for Shadows, and in no way is that depressing.

        DMM - Best Biners In the World, Hands Down

          Without question, DMM manufactures the finest carabiners made anywhere in the world today, and these are no exception. I use these for general rigging and for locking draws, and they are awesome. Silky smooth lock and gate action for easy clipping, keyhole notch-less gate closure for snag free operation (great when trying to unclip a draw from a crowded gear sling), and almost unimaginably light weight make these the best general purpose lockers you'll find anywhere. Plus, they're drop dead sexy! Sure, you can get three BD quicksilvers for the same price, but you'll die a little inside every time you try and use one of them. These will set you right! Totally worth the price.

          I need a carabiner for boats lifting. The boat (j/24) weight will be 1500 kg. So need to be a carabiner that takes at least 15KN of working load. This one says that it will hold 24KN at the direction that I need. Since it is made for climbing. The project idea is for impact. Not exactly a working load idea ... But can I trust it for the need I have?

          If you need multiple biner's, get these ...

          If your lifting the entire boat with one biner, be safe and get a steel biner ...

          This biner is priced high because of the brand name and the locking type. You don't need this high priced biner for your application.

          Pretty much all of the climbing biners are rated really high to handle an impact fall, which generates way more stress than holding a weight. Do what the others said and get some cheap steel locking carabiners. They'll be plenty strong and save you some $$.

          I need a carabiner for use in a hunting...

          I need a carabiner for use in a hunting tree stand. The biner will be fastened to a harness in case of a fall. I assume the biner should withstand the force of a body falling 4 feet because it was make for rock climbing, but the specs do not list a maximum working weight. I am not familiar with how the specs provided correlate to maximum working weight. Will this product do the job?

          These climbing biners are rated for climbing falls, I'm sure they'll work. 24kN translates to 4800 pounds of dead weight, so as long as you use a dynamic line (which you need to anyway), then you'll be perfectly fine. I've only seen a carabiner break once in a real world situation, and that was trying to tighten a slackline with a car.
