A multi-functional, lightweight and compact keylock locker, the Black Diamond Positron Screwgate CarabinerΓÇÖs low-profile, non-snagging nose is easy to clip and clean.
I use these carabiners for my PAS as well as for anchor building. They're small but have the same force rating as the larger biners. I use these for everything but the biners that I run the climbing rope through (since their edges aren't rounded).
