Which is thicker?
|
A rather simple question, I think, but I bought cordelette and a Prusik cord from someone here on MP. And while he listed the lengths of them, I'd like to sure. So other then sending them another email, asking something such as this, I figured I'd see if it's true for all of you, too. For those who carry cordelette and a Prusik cord, which is normally thicker? I have a thicker cord and a thinner one. Depending on the thicknesses of the cords, could I use them interchangeably? Sorry for the noob questions.. |
|
the cordelette should be the thicker one. |
|
I think a prusik is supposed to be tied with cord that is half of the diameter of the rope, plus one mil? Something like that. |
|
The prusik is the thinner and shorter one. It's thinner to grip the rope when tied as a friction hitch. The cordelette is longer and thicker since it would generally be used to build anchors. Length for linking your pieces together and thickness for strength. |

Most would use the thicker stuff for cordelette. If you think about how and why they are used, this should make sense. |

Typically a cordelette is 7-8 mil, which would probably be too fat to work well as a friction hitch.Half the rope diameter works well, generally 5-6 mil works best for people. 7-8 mil will work but you need way more wraps for single line for it to be able to "grab". |

Cordolettes are for building anchors. Most of mine are Ø7mm. |

Woah. Fast replies. That's pretty solid. Alright, well, I took a picture to show you all. The blue one has a knot in it, possibly just to hold it together. The other doesn't, and is much thinner. Time to read your replies though. |

The difference in diameter between your rope and your prusik allows the prusik to cinch better. If you ever have to rappel on a thin diameter rope like a 7.7mm twin rope then its a good idea to have a thinner diameter prusik cord. I would recommend purchasing freedom of the hills as it covers a lot of topics.Freedom of the Hills is on my list of books to purchase. But I need a new laptop, as well. So FotH might have to wait.. |

Thinner and softer is best for prusik. But, Klemheist is more versatile. |

New laptop: $1,500 |

I'm sure someone will sell you a copy here in the for sale section for cheaper than retail... |

So 20' of 7mm cord for a cordellete is $9, and 10' of 5mm cord is $3.50. There, $12.50 for brand new cord. One cordellete, and 2-3 prussiks. Look before you buy. |

I use an eight when canyoneering but never for climbing anymore. Maybe the 8 gets used for winter mountaineering? |

But yeah, I get what you guys are saying, check everything out and get/keep your priorities straight. You do it nicely though. Did I just jinx myself? |
