Pricy for what you get

  • Familiarity: I've used it several times

Standard oval locker. Screwgate is pretty smooth. I use a couple to clip into the bolts for my anchor systems. Keylock is nice and snagless making anchor setup a snap. Ultimately, there are cheaper options in both oval and D-shape carabiners.

Good when ya need 'em

I use these for hauling with a Mini Traxion to keep from cross loading, and on my daisies when aiding to get the best of the oval (to prevent pant-soiling 'biner shift) and the locking mechanism (for jugging). The keylock is seriously nice when you really don't want to spend a whole pitch getting snagged on wires.

Nice Carabiner

Nice caribiner, the color rubs off pretty fast, but it does it's job.

Gotta have 'em

Love the screwgate for a locking oval for anchors, top roping, etc. Very clean design and well made.

Great on a pulley

When using pulleys you cannot beat an oval krab. The automatic action on the Traict is smooth and simple to use whilst setting up. It also means that the insecure gorilla you climb with will not be able to tighten it to the point of no return. The only downside I see is that you really need both hands to operate the action. The lock can be twisted and opened single handed, with some practice, but it is not a simple affair.
