I spend most of my days as an indoor gym climber and when I can, I do outdoor climbing. The Petzl William (Specifically Triact-lock) is the type of caribiner that I always use. Again specifically the locking mechanism. Iβve used it over screw gates and just wont go back. I purchase the William for 2 reasons, #1, The tape (for figures and hands) fits great on the wider section of the William. Its much easier in getting the tape to unroll. #2 and most important is using the Munter Hitch (Knot) in Belay and other climbing scenarios. The large caribiner allows for the knot to rotate easily for lead climbing etc.. Its a fantastic caribiner and I have not complaints. Some say its a bit costly but you get what you pay for.

I chose this one over a different brand because side by side there was a significant difference in how smooth it was to screw the lock up and down. This brand I could easily screw the lock up and down with one hand, the other one was a challenge and would bind. This one was zero bind. Me like

I purchased the X3 bar but just couldn’t justify the price point…I found an alternate bar (will post separately) and these carabiners…..which perfectly match up with the larger bands. You’ll get a reasonably close set up as X3…with a bit less convenience…at 1/5th of the price….worth the investment….good luck

Perfect for rope attachment to slings on stations and for attaching ATC/ gri gri to belay loops. The red marker that enables you to see at a glance whether it’s locked is also a big plus.

I love these carabiners. I keep these carabiners handy whenever I’m camping or kayaking as they work well with securing things together or attaching to bullies. They’re pretty heavy weight and can handle quite a bit (had them holding a heavy-ish backpack to my hammock and they helped me secure a kayak that overturned when kayaking on the nearby river).Now the pro of the locking system is that if you’re worried about it unlocking unexpectedly, you shouldn’t. The locking mechanism requires some intentionality to undue. That being said, if you’re trying to find something that can quickly release if needed, you’d do best with a different carabiner (perhaps with a straight up large wire gate).One other thing that I would mention is the area provided in the bent hook portion of the carabiner limited the amount of large items you can have on it and the locking mechanism is kinda chunky so whatever you put on it needs to have a reasonably sized opening to clear the mechanism if you want the smoothest experience.Overall, I rate the carabiner 5/5, I would buy again if I needed another carabiner with a locking mechanism.

I use this carabiner for an outside-the-box application. If you’ve ever traveled around India on a train, you know that kids jump on and off the trains as they slow down in populated areas. Most of the time, they are selling stuff. Occasionally, they are looking to grab an unguarded backpack and jump back off the train, leaving the victim SOL. Or maybe you’re on an auto rickshaw in Southeast Asia and some kids on a motorcycle drive up next to you, grab your bag out of the rickshaw, and disappear into the congestion. Again, SOL. Any carabiner (together with a tech web sling or runner) can anchor your pack, making this type of theft difficult if not impossible. What makes this carabiner a particularly good choice is the TRIACT opening mechanism, which is quick to operate if you know how it works but slow and fiddly if you don’t. It adds friction for thieves without inconvenience for the user.About the only thing I don’t like about this carabiner is the quality of the finish. Petzl uses a durable satin finish with their other color choices. This black is the opposite: a matte black that is easy to scratch. This doesn’t really matter when the carabiner is used for its intended purpose but, for my application, isn’t great.One other note: I purchased three of these and all of the TRIACT mechanisms were well-lubricated enough that oil drained out of them for a few days.

Best brand name. Very strong and reliable. And always good looking. They have done the product research and testing. And that’s why you pay the price you do!
