Great for Racking Nuts

Keylock oval biners are great for racking esp nuts/stoppers. These do the job and are the lightest, full sized ones I could find. Good kit.

Okay Oval

Familiarity:

I've put it through the wringer

I needed oval carabiners for my rope clamp (the manual specifically said I should use an oval locking carabiner). If I had a unlimited fund, I would have bought Petzl OK locking carabiners ($24 per piece), but since I didn't, I had to settle with Mammut Wall Micro Oval Locking Carabiners. Which is not to say Mammut Wall Micro Oval carabiner is inferior. It's not outstanding, but considering price and brand reputation, it's a solid carabiner. If you are looking for a decent oval carabiner, but can't spend too much money, this is a good choice. Could be slightly bigger, but the name literally had the word, "micro", so I don't know what I expected.

My Preferred Oval

Familiarity:

I really like this oval for racking my passive pro. Size: Full sized and does everything I'd like it to do. Gate: Plenty big and very smooth. I light the smoothness of it. Nose: The nose has no notch which is what I prefer so my stoppers don't snag on it as I'm taking the pro off the biner. I've been on an alpine route in the dark when a partner had a carabiner snafu and the entire set of stoppers dumped out on the route as he was cruxing. Weight: Definitely not the lightest carabiner on the market but no terrible. I like these for my passive pro becauase I can differentiate my passive pro from my Neutrinos (C4's) Trango Phase biners (Master Cams) and my Nano 22's (Mach Express draws). So it's a bit of color and geometry that helps me keep things organized. Racking: I have three of these Mammut Ovals to rack my stoppers and DMM Offsets. I prefer these over other oval's because of the smooth gate and the lack of a notch in the nose which would cause my pro to catch as I de-rack it. Shoot me an email anytime you have questions about the Mammut Wall Micro Oval or any other gear! Jared D. Expert Gearhead 801.736.4336 jdowns@backcountry.com

Heavier than it looks. Solid otherwise

Even knowing this was 2oz, it's slightly bigger and heavier than I thought. Whatever, it looks nice and is pretty good for racking nuts and other trad gear, the keylock means the wires don't get caught, although I could easily use something smaller. Occasionally use two of them for a top rope anchor. 4 stars for nothing mindblowing but a solid biner.

This picture does not show a locking carabiner, so which is it?
