New rope — is this actually a defect?
|
Hey, want to crowdsource some opinions — I found an irregularity in a rope I just bought that I’m concerned might indicate a defect. The folks at Backcountry say it’s a normal thing, but would love some outside options About 6 stitches in the rope are larger than the rest and slightly bulge out with a little fraying. The core feels fine, but anything that seems off with a new rope has me concerned about its safety. Is this a normal thing? |
|
I don't really have an opinion on whether or not this is ok, but I'd suggest reaching out to the rope manufacturer for a more definitive opinion than from Backcountry. |

It is a splice in the sheath yarns. Nothing to worry about. Search for air splice here; there was another thread on this same thing a month or so ago. |
|
From that Sterling page, it looks like an air splice is used where a rope changes pattern or color.The OP's rope looks all the same color and pattern. Why would there be an air splice on that? |

definitely retire the rope. I’ll pay the shipping to my place for proper disposal :) |

Yeah I commented in the other thread that it was an air splice, and that they only use them when they change colors or pattern, but I was probably wrong about that part. That was just what bluewater told me about their ropes, but as far as I know, a rope company might use them whenever they run out of any yarn/thread. |

A slub. |

Thanks for the input y’all! fwiw the rope manufacturer (Black Diamond) hasn't been at all responsive when I reached out about it, but consensus everywhere else seems to be that it’s safe. Appreciate it! |

You could entirely remove the sheath of that rope and it would still hold. Ropes are designed with a series of weaved core strands and an outer sleeve (sheath) to protect those strands. Any defect or damage to a sheath is like scratches on your car. They do not affect the engine. Once you see white or feel soft spots inside the rope you should worry. It is a good idea to feel the entire rope as you flake it. Soft or inconsistent feeling or the core can signal crushed or damaged core strands. |

Same thing. Same rope. Rope is 2 months old and has been barely climbed on. Only indoors. One soft catch on an overhung route did this. I got mine at REI so will return there. |

Eva Williams wrote: Definitely damage caused from use and not the same thing as OP. I understand REI's policy but it seems wrong to me to take it back there for a refund and send it to a landfill when the rope was perfectly fine. Pulling a rope over a sharp edge will cut it, day 1 or day 1000. |

Eva Williams wrote: That doesn't look like the same thing at all. OP's rope has a thicker bit of the black fibers feeding through, which then seems to end. Your rope has both blue and black strands cut, in an area that crosses a bunch of fibers (i.e. it's not just the fibers ending). I don't personally see any issue with returning items to a big corporation if you can, but I will say, there's no way this is a manufacturer defect. It's pretty clear that this was caused by some sharp edge, and if I were you, I'd talk to the gym where this happened and see if you can find/replace the sharp edge so this doesn't happen to someone else's rope. |
