    Redundancy is the name of the game when it comes to climbing anchors, so let the Petzl Am'D Locking Carabiner back you up when it matters most. The Petzl Am'D comes in three different lock modes (Screw-Lock, Ball-Lock, Triact-Lock) to fit your needs. It has a keylock gate to ensure it won't snag on your gear when you're building an anchor.

    Nope try again.

    • Familiarity:I've used it several times

    There are other self lockers that you can spend your money on. I would not recommend this as a locker to use on a climb. The only thing that I would use this for is maybe with your ATC device but you might stuffle getting if off of you. It's really difficult to unlock in general. I wouldn't even use these for my keys. If you need recommendations on a locking biner look at the screw gate version of this or ANY other Petzl biner that they have.

    Works well after you figure it out

    • Familiarity:I've put it through the wringer

    The tri-act lock is great and I have no trouble opening it with one hand, the only annoyance is sharing it with other people who always struggle to open it. I spent 20 minutes watching TV and fiddling with it and got the motion down, and I don't have particularly large hands or anything.

    I've used this carabiner as my main belay device biner for a couple years in dust and sand and dirt and the action still feels plenty smooth.

    Blah. Not a fan (Triact-Lock)

    • Familiarity:I've put it through the wringer

    So I'll start by saying this is a nice locking biner and I have two of the Triact-lockers. But, woof. Such an incredible pain to use. Other thing I use them for now is when rappelling and have a prusik.

    Other than that, I am not a fan.

    The material is great. The product is durable. The the motion to open the gate on this biner is next to impossible to do single handed. I've done it with one hand, but it's not easy nor consistent.

    Maybe it's time to try one of the other variants?

    My first and last ball lock carabiner

    • Familiarity:I've used it several times

    I have started to use Petzl Am'D Ball Lock Carabiner couple of years before and decided that one ball lock was more than enough. Because I have experienced difficulties to operate it in winter condition. I guess, if you would use it for some "long-termed" fixed points, it might be good.

    Screw lock

    • Familiarity:I've used it several times

    Screw lock, screw failing, this thing is built to last.

    It's sleek and good looking. It's also a little larger than I expected and larger than my BD positron carabiner, that can be a plus and negative in some cases.

    It's also a little bit heavier than similar models/carabiners (73.7grams) but i'm not one to worry about weight too much.

    Look elsewhere

      I have no doubt this is a great biner. Just DON"T get it in the tri-act lock mode unless you only climb in the gym. I used this only twice now and it's frustrating as #@$% to work with compared to others. I like to be able to open it with one hand, as I might be gripping my axe in the other. And it's nearly impossible for this.

      Finally it's okay to be a lefty!

      • Familiarity:I've put it through the wringer

      I recieved one of these as a gift 2 years ago, and haven't bought a different kind of locker since. I have both the classic anodized model, and the stealth matte black also. The double action is really nice, and the action of the gate/ lock mechanism feels great, and has an audible click when it locks. This is one of my favorite pieces of gear. As a lefty I have a lot of trouble with omega jakes, and some of the other auto lockers on the market. I can operate the am'd one handed with a little pressure and my thumb. I use these on the ends of my tree climbing lanyards, on the end of my personal anchor system, and anywhere else I can put one!

      Workhorse Locking Biner

      • Familiarity:I've put it through the wringer

      First off I'll just say that I prefer the Peztl biners to any other brand I have tried to date. The screw action on the Am'D is not as good as is on my Williams or Lockers, but it is significantly better than the BD screw locks I have tried. Also, red unlocked indicator is a life saver on a screw gate locker.

      This is Petzl's most affordable locking biner and has a nice high volume D shape. I think this workhorse will serve you best in anchor building/management or setting up a top rope. If you're looking for a belay/rap specific biner, I would check out the Attache.

      what is the recommended life for a 'D' type carabiner

      Best Answer

      There really is no shelf life for a carabiner. One major indicator is how much it is worn through. Tests have shown biners pulling to full strength even after being 60% worn, but you would obviously stop using it way before that. Probably retire it at around 20-25%. Also, the aluminum used in carabiners doesn't microfracture like it used to, so there is no such thing as invisible damage. If you can see a hairline crack in it or the sleeve itself is cracked or won't close, retire it. If the gate closes smoothly and there are no burrs across the working surfaces, then your carabiner is just fine. My dad still uses carabiners that are a good 25 years old.

      The rule of thumb is 1 mm of wear. That's the point when wear starts to compromise the strength of the piece . Once they're worn down 1mm in any area it's recommended that you retire them. Check this article out:
