If the Black Diamond Dynotron Anodized Carabiner clipped any easier, it'd pull the rope from your hand and clip itself.

Black Diamond designed the Dynotron Carabiner to make clipping as easy as possible—this ‘biner is always a welcome sight after a long runout or energy-sapping crux. The Dynotron's snag-free keylock system assures fast clips and makes it easier to clean overhanging sport routes.

What size rope will it work with? 1/2", 5/8", and or 3/4"

Responded on

The gate opens to just under an inch (for the bent gate, less for the straight), but since most climbing ropes are 10mm or less these days (a little under half an inch), it's not geared to bear huge amounts of weight from a big rope. I'd say 5/8" is the biggest you'd want to run through it.

smooth clip

The key lock feature is great, I use these my draws on the side that clips to the rope since I don't have to worry about my fingers getting caught on the notch when I’m not thinking and pumped out.

the hotness

Super nice clip, sweet rope interaction (cleaning, gate clearance). Hard sport routes? Amazing to clip.
