DMM, Belay Master 2
Ingenious part, because it has an anti-twist protection, which at the same time secures the screw cap against opening. Perfect in the climbing gym and in the climbing garden, compatible with most belay devices. But that's not all: in alpine climbing, when the clip is rather annoying, it can be easily removed and turns the carabiner into a normal HMS.
