Black Diamond Nitron Screwgate Reviews:


I have recently bought a few of these, I always double check the manufacturers weight claims of climbing gear due to previous verifiable inaccuracies I have read about in gear reviews by even the most revered climbing brands. One biner weighs in at 52.1g, the other at 51.4g on my scale as an FYI for gram counters, rounding down to 50g is inaccurate according to my scale anyone else can verify or provide other info but this is what mine says. Is 2+/- grams per biner significant? Probably not, here comes the BUT... this leads to questioning ALL of the other given specs of the biner. If the weight claims "prove" to be inaccurate how can one cross compare all of the other factors of the biners attributes (Major Axis Strength ex.) with any confidence in the posted numbers? Should it be the consumers responsibility to test the specs for accuracy?

I love these. I don't use it to belay, but I use it as part of my anchor system as the violet haze is distinctive. It is super light, feels strong, and matches my quick draws in size and looks lovely against my nylon slings. I also have the yellow vaporlock biner, that I also enjoy. My question is, if these purple ones are 1g lighter, how come they are rated at a higher strength? The answer is their smaller size, not as much length to break, and not as much mass. Regardless I hope never to be close to the breaking point. I get protective of these, yet I love sharing them. No problems with screwing and locking. Locks smooth, doesn't get stuck, a beautiful shape of the spine and all the dimensions.

I just got 6 of these beautiful little biners and they have immediately become some of my favorite carabiners ever! They are super light and make for great anchors for setting up top ropes. They are super easy to clip due to the keylock nose, there is never any rope snagging, which is the last thing you want when you are nearly pumped out on lead going to clip your anchor. I have 4 of these for my anchors and the other two on slings that i use to clip in direct to clean and set up rappels. These are great lightweight little locking biners, get some to add to your rack and you won't be disappointed.

Insert angelic choir of rapture here. Picture me inappropriately caressing and kissing this irresistibly desirable little siren of a temptress. One thing that sucks a big one about most lockers is that they weigh about five thousand pounds, and are about as sexy as a tipped over porta-potty. This is not that locker. It is purple, slender, light-weight, easy to clip, and makes you ten percent more beautiful just by clipping it to your rack. Seriously though, this is the best locker I have ever used... I frigging love the thing. Picture miraculous rays of light glinting and flitting upon said Biner, as harp music echos delicately in the background.

Cedar Wright at on 07/13/2012

For a screwlock keylock biner these are amazing. They're unnoticeably smaller than the positrons with a much thinner nose and slightly larger gate opening. This means, you'll never snag them on anything, period. They actually remind me of the petzl spirits in shape/function of the keylock nose, but I honestly prefer the nitrons overall shape.
If you get them w/o the screwgate, they're amazing for your standard quickdraw bolt/rope end biners. Super light with smooth clipping is just a perfect combo.
For every function these truely will be snag free.

Great Biner

I have five of this Carabiner at this time! and really like it. Its lightweight, easy to open and close. Its small however it easy to handle. I use this for my Anchor also for my Prusik Cord. It does not get on the way when you have many stuff going on and it is very easy to handle. The best thing is the great price for how light it is and for the great quality

I love these caribiners! They are the best for cleaning and for making locking draws for the chains at the top of a sport route. They are small and lightweight so they don't weigh to much when I'm on a sport route and trying to conserve weight. These are awesome biners and I recommend them if you want to save weight and stand out at the crag (thus the purple color).

Good Product For The Money

I purchased (2) of these screw lock carabineers for use while backpacking. I use them with my hammock and for all load bearing situations. They are just the right size for all around use. The screw locks are simple and easy to use. I have never been unsatisfied with the purchase of anything from Black Diamond! They make great products across the board.

These carabiners are amazing. Excellent gate action, great handling, rad color, and the perfect size for many jobs. Essentially the positron, but 6 grams lighter. However, the positron is still the workhorse of my gear when it comes to lockers, you just can't beat the bang for the buck. If you've got a few extra dollars to spare, these are awesome.

Thomas Ogasawara at on 03/09/2012

Just like everyone else said, these are light! They have great grip/feel too! I already have a bunch of positron lockers I use for anchors and what-not, and I love them. Not sure if the Nitrons will be replacing anything, but they are a nice light-weight addition. Looking forward to see how they hold up.
