There should be a couple Black Diamond Light D Carabiners on every trad-climber's rack.

Although some may think it's old school, the Black Diamond Light D Carabiner works in places where other carabiners just don't get the job done. Its small diameter nose fits through old bolt hangers too small for most 'biners, so you don't get to the end of a long slab runout only to find that you can't clip the single buttonhead. Its simple shape created a strong 24kN breaking strength. The Black Diamond Light D Carabiner also works great for racking stoppers and pins.

Functional biner

  • Familiarity:I've used it once or twice and have initial impressions

I bought this primarily as a bail biner. The low cost and easy action made it perfect for the job.


Great Little Biner!

  • Familiarity:I've used it once or twice and have initial impressions

Great for racking gear, or clipping your shoes to your harness. I can see this biner coming in handy if I ever have to bail. Some immediate reactions after getting this biner in my hands:

- It's heavier than I thought it would be

- It has a notched nose (for some reason I expected it to be a smooth nose)

- Reminds me of a carabiner the Army would use


great for racking stoppers

  • Familiarity:I've put it through the wringer

use it to take my stopper set when trad climbing, and most of the times if i have to leave a binner at a rap station this is ti, because of the cheap price


Perfect for setting up slacklines.

  • Familiarity:I've used it several times

All around great biner that I have used to set up a slackline in the backyard. Makes it an inexpensive way set up a slackline where ever you please.


Solid, simple and does it's job

    I use this for anchors, third hands, hauling gear and everything in between. Nothing fancy or ground breaking, just a simple, solid biner


    Simple, durable.

      Bought this to secure excess gear and act as my general purpose carabiner clip. It's nice and light, but super durable as well. No problems with it so far.


      No frills, gets it done

        This is your basic no frills solid biner. They're great for a budget, and they're very shiny and pretty. Fancy multicolored biners certainly have their place, like color coding your nuts. For anything else you'd need a non-locking biner for, why pay more?


        Great, light weight biner

          I love these biners. And for the price, you can't beat 'em. I work on ropes courses and these come in handy for gear biners and for quick connectors. Wonderful. Would buy more.


          Solid Good Biner

            I use these biners on my runners that I use at the chains atop sport routes. I like that the biner is thicker to cater to the wear the rope puts on it when TR'ing. The gate is nice and wide which is nice. Looks pretty sharp as well. Definitely recommend this carabiner.


            Compare and come back for these

              These ain't the greatest thing since TP, but if you just need some good priced lightweight gear these will be in your bag. I have these and the standard Black Diamond D biners and for 3kN difference in capacity the weight of these makes up for everything. The "heavy duty" biners feel like double the weight in your hand. Don't get me wrong I do not use these when rapping, occasionally somewhere in my climbing setup I'll stick 1 or 2 for a backup. The term "light" makes me superstitious when I'm hanging a hundred feet over nothing, but nonetheless i keep 4 in my bag & 2 on my pack for general accessories.


              Great biner for the price!

                For the Price this is a great biner to use for keeping your shoes together, putting your chalk bag on your haul loop, or even just keeping a couple with you incase you have to lower of a (cheap) pice of gear on a lead climb. They are a bit heavy but they last forever.


                Whoa, Shiny

                  Cheap, strong, functional. Check, Check, and Check. If you're worried about weight, go for a wire biner. If you're worried about hooking you're rope or gear when unclipping, go for a keylock. If you're a cheapo like me but still want great functional gear, this is the way to go. Basic and solid. If I have to bail on something or leave gear behind too, much less painful to leave one or two of these behind (costs less than the post climb pitcher of brew). I've accumulated a number of random biners over time (some of which cost almost twice what this one does) and this basic one still seems to be one that gets used just as much if not more than the others.


                  Great Biner!

                    I use these along with my bent gate BD Quicksilver biners to make quickdraws out of 4ft dynema slings for trad climbing. They are cheap and work great! The only thing they are lacking is color, but I can deal with that for this price!


                    Very well built.

                      for being a light carabiner, it is very sturdy when you need it to be, i expected it to be more loose, but it is strong and high quality.

                      definitely worth the money even if i'm just going to use it to hold my chalk bag to my harness or shoes together.



                        Good biner. It does what it's supposed too. I keep a couple on me as bailout biners if needed. Nice and lightweight.


                        Old Standby

                          This is a great utility biner for all kinds of uses. Lasts years and years...
