Static Rope for Top Rope Anchor

This is described in the AMGA Single Pitch Manual Falconguide. It allows you to access the top rope master point or just rap down. You use the static rope to set up a toprope anchor that extends over an edge, but with the extra rope, you put a knot in it and drape it over the edge too. You then rap down that line with something like a Gri-Gri, and then transition over to rapping down the toprope when you get to it. |

Thanks for all the replays. would either of these be a good first climbing rope? |

Wait...10mm and up? |

Am I gonna die?20 ft of 7mm (a cordellette) is fine for an anchor as long as it it built correctly. A thicker line is just more durable over time and might make set up a little easier. It makes sense for guides to want something burlier for their specific uses. AMGA standards-- while good to know-- are overkill for many situations in recreational climbing. Jim |

JimOf course 20' of 7mm (aka a "cordalette") can be fine in many situations. I was responding to the blanket assertions / implications that 10mm static is always overkill, and that the AMGA advocates the use of 7mm cord all the time. Neither is true. What all AMGA courses teach is the concept of application: Selecting the right tool or technique in the right place and at the right time. There are no one size fits all solutions in any of the AMGA training curriculums. |

Please don't use a bowline, it's a death knot. Many "accidents" have resulted from the use of a bowline. |

I agree with the posters above. EMS or other climbing shop and buy X length of 10 mm static rope. I have a 90ft static line I use for tr anchors and have never needed more than that. I started out using tubular webbing but found it to be a pain in the butt and waste of money. |

I use webbing, since it is lighter, but static line anchors are bulky but fine. They are really tough and less likely than webbing to get chewed on if you leave them up for a while. Regarding the dynamic rope, it's OK, but get a 60 meter. You could go with a 10 mil rope as well. More importantly, see if you can find a deal on a bi-pattern. Because the middle mark is woven into the sheath, it makes setting up a top rope much safer and won't wear off. Here,s one (although I like your first brand better): backcountry.com/sterling-bi… |
