Description

Well-versed in the prose of climbing.

As the saying goes, 'jack of all trades, master of none.' Black Diamond built the Nitron Screwgate Carabiner to re-write that to say "jack of all trades, master of all of them.' This do-it-all 'biner features a keylock gate that won't snag on protection, slings, or hangars, while small spine ridges and ergonomic shaping make for ease of handling. Whether you're headed to the frozen waterfall or local sandstone crag, rack up a few of these renaissance 'biners.

Gear Differentiation

  • Familiarity: I've put it through the wringer

These are lightweight, safe, easy to use, blah blah. I've been trusting BD with my life for ages and have no worries about misplaced trust as far as function goes. The reason I got these screwgates in particular was for their color. They are a very distinctive purple which keeps my climbing partner from taking them home (he is constantly confusing my gear for his and then never gives it back)!

No problems after a year

  • Familiarity: I've put it through the wringer

These are my go to locking carabiners for cleaning anchors. I've had two of these for nearly a year and haven't seen any degradation in the screwgate or the carabiner itself. Highly recommended.

Inaccurate weight description

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?

Responded on

Well, let's assume they round down approximately 2% (1g/50g), that gives you a major axis strength of 24.48 kN. Even assuming they rounded UP by 2%, you still have a major axis strength of 23.52 kN. Not sure about the whippers you're taking, but I'll take my chances with 5287 lb of force before the thing breaks.

Give it a rest, there are manufacturing tolerances, and these are within them. You're going to be safe. It's Black Diamond gear.

Responded on

I did not imply the safety of the device being compromised by the "manufacturer tolerances"those are your assumptions of the statements I made. The questions I purposed are in a whole other realm of thought granted they were presented in the wrong place for such discussion.

I am writing very simply about the ethics of correct product representation. A simple +/- X.Xg or X.X% in the description would be the easiest fix but since that is not the case here are my thoughts.

I only measured two and at 2.1g heavier then advertised, I doubt I own the heaviest made. So if BD marketing chose to advertise 50g due to it being the average weight then we are talking a potential range of at least 47.9g - 52.1g for the extremes and highly likely to be more in either direction. If the average weight is actually higher then 50g then I feel any "rounding down" to be a product misrepresentation no matter how little. Sure our simple minds LOVE whole numbers and especially factors of ten, but I learn more towards accuracy myself. Anyone reading this should grab two comparable biners of the same model around 50g in weight and a nickel coin(5g). If all this gibberish has any "weight" ;P then the potential difference at the extremes between biner A and biner B (of the Nitron specifically) could be greater, equal or less then the weight of the nickel.

Responded on

I will state AGAIN, does this matter for the actual use of the product? For 99% of consumers probably not. Can there be a reasonable "manufacturers tolerance" in weight variance? Of course. Should there be any "marketing tolerance"to mislead product info? Definitely not.

I am not accusing or picking solely on BD as they are one of my favorite and most respected companies for many reasons. I am simply pointing out a trend I see with a variety of manufacturers with my LIMITED amount of data. Products run heavier 90+% of the time. This is why I question advertised weights of EVERYTHING, are they based on the true average or what a marketing team decides is within their maybe self appointed range of tolerance?

Without consumer criticism the manufacturers have an imbalanced amount of control over where the bar is placed so no, I will not give it a rest.

Responded on

I understand your concerns completely, and I agree for the most part. If the majority of Nitron carabiners are in the 52g range, they should state that, not the lowest known specimen and absolutely not any type of fabricated numbers. There are several possible justifications, such as your scale being uncalibrated, unanodized or unpainted equipment being measured, certain batches including more material, typo, etc...but I won't say that any of those are definitely the issue, who knows? But you're right in that regard, the weight should be correctly represented.
HOWEVER, you specifically and blatantly call into question the validity of the strength of the biner because of a small weight discrepancy in the final few sentences of your review. I comprehend the extrapolation that a misleading weight measurement may indicate a flawed strength measurement, but think about what you're implying. Does the weight of a carabiner put in danger the life of a climber? What about the major axis strength? I don't think I need to answer those two questions. Safety is something that companies take very seriously, and I'm pretty sure BD is not misrepresenting strength numbers. It is my understanding that they proof load their biners to 50% of the stated strength. It is unfair to assume that because the weight measurement is off by a small percentage (in a direction that would favor a greater strength), the strength measurement is invalid.
If you really want to make a stand against Black Diamond's misrepresentation of the weight of the Nitron Screwgate Carabiner and its correlation to the strength of the biner, I suggest you back up the ultimate strength of the biner with your own personal data. Get it tested. If you are really that worried about it, I'm guessing they'd even test it for you and give you the results. Until then, it's just assumptions.

Responded on

I am not stating that the mass of a product is directly proportionate to the strength of the item. My mention of "major axis strength" was a random attribute that I arbitrarily picked of the several possible in my explanation that was directed towards marketing of the item not its physical properties. Please re-read and understand we are not on the same page and you skew the meaning of my comments with this imaginary tangent.

Responded on

Duh. However, this IS what you said:

"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?"

Because of your claimed measured inaccuracy in the weight/mass of the product, you call into question its strength. This, without proof, is not a valid assumption, and you sitting here and calling out BD with no real proof isn't cool. That's all I'm saying.

Responded on

This will be my final comment on the matter because either 1) You are truly misunderstanding my statements in their entirety and possibly leading others to a false understanding of my initial comment, or 2) You are the least funny troll, ever. Imagining #1 is the case, here we go!
Firstly you think that for an assumption to be "valid" it must be backed by proof? If I had proof of anything it would not be an assumption ..
Secondly I was not even going as far as making an assumption (accusing) of that single specification being wrong, I was calling into question all posted numbers of all products everywhere, which is far lighter in accusatory means.
Please don't get caught up on the one example I used as I am speaking about a bigger picture. I was basically implying that consumers should not follow any manufacturer with such a religious zeal that they are blinded to possible inaccuracies in product descriptions whether unintentional, industry tolerated, or intentional.
For all of our fellow backcountry men and women that took the time to read our silly rambling I apologize for using the comment section here to address something so off topic. I hope you were entertained, at least! =D

Well, at least you got the last word, right?

Are these larger than the BD Rocklock...

Posted on

Are these larger than the BD Rocklock Carabiners? Someone mind tossing up a pic of both next to each other?

Responded on

Don't have a picture of both, but here are some more specs. Nitron: 1.8 oz, 22 mm gate opening. RockLock: 3 oz, 21 mm gate opening, munter hitch compatible. Closed, open, and minor axis strengths are the same for both and both feature a keylock nose for smooth clipping.

Responded on

No, these are much smaller. Nitrons are standard D-size carabiners, Rocklocks are much larger.

Great Locker

  • Gender: Male
  • Familiarity: I've put it through the wringer

Everything about this biner is solid. Gate action, weight, locker, color, everything rocks. Great for anchors and for clipping into the chains. Purple color also really stands out on the harness.

wish I was as light, strong & lavender

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.

Great Lockers!

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).

One Sexy, Purple, Bad Ass, Beast.

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.

B-e-a-utiful

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.

When a positron goes on a diet...

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.

So light!

Great "crisp" clipping. The best lockers I've got and they are SNAG FREE!

Light and easy to clip

Not much else to say except that they are light, handle great and have the keylock nose.

so thin. .

so thin. .

biner is 4 exactly inches long down the spine.
nose is 1 cm wide at the tip and 2.5 mm until the I-beam shape starts.

snag free, oh yea

super light

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.
