When you're pumped stupid and digging for that crucial cam, you'll be glad you racked up with the Black Diamond Oz Rackpack, which features six hot-forged Oz carabiners, color-coded to ease cam identification. Our HoodWire Technology uses a patent-pending stainless steel wire hood to bring keylock functionality to wiregate carabiners without losing the lightweight and anti-freezing benefits. And thanks to the Oz's optimized geometry, it holds strong as the lightest carabiner in our line.

  • Hot-forged construction
  • Patent-pending stainless steel wire hood design doesn't snag, eases clipping and cleaning
  • New optimized shape
  • Same size and clip-ability as the Neutrino, but 8 g (.3 oz) lighter
  • Anodized in Camalot and C3 colors for easy identification
Hot Forging vs. Cold Forging


We use two different forging methods to build carabiners—hot and cold forging. Each has its benefits and using both allows us to achieve the best possible shape, size and strength for each carabiner’s intended use. HOT FORGING, a process where both the rod stock and forge dies are heated, allows us to “move” the metal, creating more intricate shapes, such as our GridLock and Oz biners.

Rated 4.5 out of 5 by 8 reviewers.
Rated 4 out of 5 by Weight drop I love the feel of the Oz, holds well and gets rid of the gate hook found on the Neutrino and similar carabiners. And it's lighter! Now if only we could get individual coloured Oz biners. July 30, 2014
Rated 5 out of 5 by Airy Awesomeness Light weight with a fully hooded gate. What more do you want? Smooth action. Versatile, good for most applications, though a bit small for clipping. Big improvement over the original Oz. Plus they're awfully pretty. July 13, 2014
Rated 5 out of 5 by Perfect for racking cams The Oz carabiners are really light, easy to clip & unclip, and the color coding is really convenient for racking cams. Couldn't be happier with them! June 17, 2014
Rated 5 out of 5 by Oz Is As Light As Gauze After being a frugal climber for many years and transitioning from bouldering to big walls, I found my cheap choices added up in weight. With a single or double rack, you will be happy you switched to Oz biners. I keep having that sensation that I forgot something, but it's just a lack of weight. They also handle really well and color coordinate. Thanks, BD. April 19, 2014
Rated 5 out of 5 by racked up Perfect light weight biner for racking the camalots. Maybe I got lucky with the 3 racks I bought because I have not had any of the problems that other reviewers have had. They have worked flawlessley for me and I will be buying more November 4, 2013
Rated 4 out of 5 by Impossibly light I am really impressed by the lightness of these biners. The hoodwire is a great idea as well. This is my go-to rack biner, and I have several packs, but I give it 4/5 because: 1) The hood doesn't cover the tooth _quite_ enough, so it still snags on webbing sometimes 2) The gate opening action is not all that great. Some biners won't open all the way without undue force, and most of them are quite stiff If BD ever decides to tweak the Oz and improve these admittedly minor issues, it would be a perfect biner to me.

Rated 3 out of 5 by Poor quality control I have found out that I am not the only one where half of the rack pack has very stiff gates. I loved the hoodwire and liked the new Oz so I threw down the cash for two rackpacks, but found that half on each are really stiff, not my favorite when pumped out trying to clip and worse trying to clip twins. Just check them each out in a store and don't settle for only some working. When they work right I agree with all the other reviews, one of the best biners out there: great function, weight and price. July 24, 2013
Rated 5 out of 5 by Couple with Camalots Perfect for fast grabs when running it out, or when lounging on stellar jams, if you have Camalots couple them. My favorite biners with color. June 23, 2013
