Now I got to say since the last Carabiner I had used I did like alot. But again all of these different types of carabiners are beeing used for many unique advantages while climbing or what ever it is your using yours for. But the Green little ball is great 👍because that must be pressed and then twist and pull. Its definitely a one handed ✋ carabiner. And that says it all when your hands are tied with rope and other equipment. This one has a nice design which allows more room for a less rope friction. We all know we hate Friction but when it comes a time where it can be acceptable. This one here is a Buy and Hold. For Treestuff.com it is a Sell Sell Sell. #TRUTREE #PETZL

That's right. J'Adore this Petzl carabiner, and I'll tell you why.As experienced climb folk, or those with basic reading comprehension skills, may know, this is a Triact-Lock carabiner. Meaning we are now dealing with a carabiner nothing short of an entire echelon superior to the Screw-Locks and Twist-Locks of yesteryear. Not only does this carabiner require initial operating instruction from a mechanically inclined wizard, intense finger strength, and an eye for the finer things in life; but also it provides unquestioned safety, a daring flash of double-orange, and a glimpse into a better world.Petzl have done the unimaginable, again. I pass no judgement, but you'd be foolish to buy any other. tom5000, signing off.

I have 5 of these, and will probably keep buying them, however, a few things for you to note before purchase.- Good for anchors- Crossloads almost every single time when belaying (bad bad bad). Must flip it to narrow side up to avoid this, which should not be the case.- The screw lock is gimmicky. DO NOT over tighten at all, impossible to unscrew. Only tighten lightly and it should be good. Too easy to overtighten which causes anxiety when only tightening lightlyIn the end I would honestly only recommend for anchors. Buy a belay specific biner to avoid cross loading.

I use these 'biners to secure anchors when doing sport single pitch. The shape, color, and typical Petzl quality is excellent. Unfortunately they do get stuck. When screwing down make sure not to overdo it otherwise you're in for quite the odyssey to re-open them. In a way that this what you want for a screw lock but this is too much of a good thing. I now carry a multi-tool (plier attachment) to ensure that I don't end up leaving slings at the anchors. Not sure if I'd buy them again for this reason. For a reference I am a 6'7" 245lb man and even for me it takes the strength of Zeus to unlcok these things if I tighten them too much. Not saying size is the end-all be-all but hopefully that gives some perspective. I absolutely love Petzl and will keep buying their ...

Used one like it for years on climbs, and then so no one would steal my dog when I left him outside to get a coffee; (dimwits don’t know how to unscrew a locking ‘biner). Assumed if anyone knew how to use it, they’d take good care of my dog. Anyway, misplaced that one while chainsawing (still have my dog) and am heartily satisfied with this ‘Biner replacement! Using it with ropes the secure trunks prior to limbing/bucking while trail volunteering. So far, so good.
I love everything about how this carabiner is shaped, feels and functions, but as other have mentioned, sometime it gets stuck and will not open. In my case, mine got completely stuck on a rappel system, and the only way to escape my system was rappel off the end of the rope then bring the carabiner home still stuck to my belay device and harness, and use some lube and a wrench to open it. This seems like a huge safety concern if someone became stuck to their system, especially if rappelling off the end of your line isn't an option. I will be retiring all these carabiners unfortunately (I have 3).After mine got stuck, I discussed this issue with other climbers in my area, some expressed that they knew people with the same carabiner becoming stuck under body weight ...

I will be retiring all these carabiners unfortunately (I have 3).After mine got stuck, I discussed this issue with other climbers in my area, some expressed that they knew people with the same carabiner becoming stuck under body weight loads. Looking more into internet reviews, it would seem that others have experienced this issue. Unless you carry a wrench while climbing, I would not recommend this carabiner.Rated one star because someone becoming stuck in a system on a longer route where rappelling off a line isn't a option poses a significant safety risk. If this was an isolated issue, I would likely have overlooked it, but it seems to have affected at least two people in just my small Midwestern town and numerous of people online.
I love these biners. Easy to operate w/ one hand and don't jam up with dirt, snow, or ice. Great for use w/ Grigris, personal anchor system (PAS), anchor pieces, you name it. Quality is top notch as always from Petzl. I've used screw locks for years and didn't used to buy into needing another layer of "locking" until I experienced a rope drag over a screw lock biner and open it. I still use screw locks most of the time, but if there is any possibility of it opening on accident or if it is a critical piece in the system I use these. I've also used these to replace my larger belay-style lockers w/ my Grigri and love it (not so much with my ATC Pilot). Pick one or a few of these up. You won't regret it.
I've had two of these for over two years and got some great use out of them. Very sleek and love them for anchors. But on an ice climb yesterday both of them had their screw gates seize in locked position. Impossible to open, belay device trapped and will need to be replaced. Apparently this is not all that uncommon for this specific locking biner. People say, don't over tighten, like it's the climbers responsibility to use the product correctly. That's garbage advice, and when it's -20 and you're setting up a belay with thick warm gloves, sometimes you can't have that feathered touch to not tighten them all the way. Contacted Petzl but will probably never purchase these again, just not worth the risk.
The William ball lock carabiner has a high strength rating of 27kn, and is on the large end of the spectrum. Still the same wide opening snag-free key lock design as the William Screw Lock, but with a button safety twist gate. I typically use this as my masterpoint carabiner on multi-pitch trad anchors and top rope anchors due to its strength rating and it's rope capacity. There's plenty of room to fit two clove hitches with a 10.2 rope. The ball lock is very easy to manipulate, push button and turn. Release the gate and it snaps shut, automatically twisting back into locked orientation. Very secure, and quicker than rotating a screw lock. Durability seems to be no issue, clacked around on several granite routes over the past year. I'm very satisfied with the ...

The William carabiner is a large frame, high load model. 27kn rating! Nice snag-free key lock design, with a wide gate opening. I typically use this as a masterpoint on multi-pitch trad anchors and top rope anchors due to its strength rating and it's rope capacity. There's more than enough room to clove hitch a 10.2 rope twice! As with other Petzl screw locks, if the lock is overtightened or tightened while weighted it can get stuck. Simply reweighting or tapping on the screw lock while unscrewing it typically fixes the issue. I can see sandy areas causing an issue with binding on screw threads, but that isn't an issue that is unique to just this carabiner, it can affect all parts with threads. Overall fit and finish is exemplary, and the red indicator band is a ... MoreThe William carabiner is a large frame, high load model. 27kn rating!
