Don’t be a cheap asshole climber: Climb X Hanger Failures

So there’s this company called Climb X. They just recently started making gear. However, for some reason, they just seem to be copying popular designs of other companies, making them and selling them cheaper than the other companies.

Among these bad products include a total ripoff of a gri-gri, total ripoffs of helium cams, rip off ocun crack gloves and ripoff madrock shoes. Incredible!

However, one of the main things is these hangers that have been seen to crack like crazy in Colombia (picture above). Here’s another photo of this horrendous hanger.

Pretty frigged up. Anyhow, this was posted in reddit, and immediately a IUAA safety guy chimed in:

Hi All, I’m a materials engineer and am on the UIAA Safety Commission. A few people directed me to these posts talking about the ClimbX hanger failures. And I believe there have been some other issues in other locations.

If someone can get some samples of failed hangers I’d like to see them. If you can do that, I can supply an address.

As for SCC, and I’m not saying the failures WERE due to SCC until I know a bit more, then the following is true about SCC: – low alloyed steel does not suffer from chloride SCC in these conditions, it will corrode, but not crack due to SCC – SCC occurs due to three things, all of which must be present: stress, aggressive environment (for SCC) and susceptible material – the stress can be an APPLIED stress, or a RESIDUAL stress due to manufacture (bending, extruding, welding, rolling, machining etc etc). Or both – ALL of the 300 series stainless steels are potentially susceptible to chloride SCC at ambient (room temperature) conditions, but you need enough time at the right relative humidity, and high enough chloride levels on the material (too dry and it doesn’t happen, too moist and it won’t either: in between and it does) – a salt crust deposited by the wind from the sea can be enough, and it can be carried very far inland (a 100km or more in some cases) – however rain can wash off the crust before it starts to attack the stainless steel, so that’s why it’s not seen more often – some environments make SCC much worse, like karst formations such as are in some Thailand coastal crags, or Cayman Brac

None of the failures look like galvanic corrosion to me, but I haven’t seen the hangers in the flesh yet

It COULD be a poor material choice like 303 grade stainless steel. It has sulphur in to help machine it, but reduces corrosion resistance.

And it COULD be due to SCC.

Need to look at some failures to be sure.

Pretty frigged up. So turns of that most of the bolt hangers at this crag are Climb X hangers and that is incredibly bad. Maybe it is just a bad choice on the climbers side but if Climb X isn’t a company that is just a worthless, job stealing, steaming pile of dung I hope they do the right thing and refund the money to these climbers so they can get real Fixe Hangers.

Anyhow, remember that when you are clipping into a hanger, it is your job to assess if it is rusted at all and if you feel safe clipping it. And maybe, if you’re committed, try to fall on the last bolt (or not at all).

Obviously I know that there might be something here, like in Thailand or other coastal regions that get hit hard by salt water spray and everything rusts fast. But I think that this makes no sense, seeing how little rust was on the hanger.

This bolt (in California) was reportedly pretty strong still (considering how it looks)

RustyAnyhow, lesson learned: You get what you pay for

That’s it!
