    Do yourself a favor and get 4 of these for your anchors per one top rope setup. There rock solid and burly big. Save my ultralights for belaying and anything else where I'll be carrying them on my person. These can take a lot of abuse and are my only preferred ones for setting up anchors. Petzl William are also a favorite to compare. Whether your starting out or looking for a rock solid anchor point, get these!

    Great pear shape, large size, makes this a great all-around carabiner. I use it all the time with an ATC style belay device. I think the diameter is a little too large for use with a gri-gri, but it is great for everything else!

    These are my favorite locking carabiners. They're a bit on the heavy side (even for a locker), but they're so easy to operate again and again, that I don't mind the extra weight. They're easy to open with one hand (even with gloves), and all you have to do is release and they're locked. They are solid, bomber, and I use them all the time for anchors, clipping on to bolts, and via ferrata routes.
