PETZL - William, Locking Carabiner for Belaying

These are definitely a more secure option compared to screw locking carabiners!

Excellent product, typical of the quality I've come to expect from Petzel for over 45 years of trusting my life on their products.

Excelente tiempo de envío y con petzl la calidad siempre es top.

Arrived as ordered. I do like this carabiner more than most of the others. It's a little bigger in the loop and just feels a little heavier. I'm going to switch this one to my main carabiner on my 1 stick setup. Will definitely order more

Muy liviano, fácil de usar, se siente seguro.

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.

Big, nice finish.

Exactly what I ordered, arrived on time, and the price was right.
