rappel cord?

[Coldfinger]

So why is there such concern over strength of the pull cord? (other than the obvious strength needs for pulling but that would be like 200-400 pounds) Why wouldn't a cord rated to 600 pounds work?

 

It's just what happens when the pulling results in a stuck rope: not much fun climbing back up 2mm cord........

I do rap on the pull cord, but I put in that fancy back-up with the knot and biner on the thick rope side of the anchor just in case the rope breaks. I don't like just rapping on the thick cord, but that really jams the knot into the anchor.

 

one trick to not get the pull cord stuck is stuff the free ends from the anchor into a stuff sack, clip it on your harness and have it feed while rappelling. This is also the cord you pull, so it shouldn't get stuck since the thick rope is the one tumbling down.

 

The negative to this situation is IF the thick rope gets stuck on it's descent down to you, you are kinda fucked if you have only the pull cord to lead back up on....the the benefit of what Mike (wallstein) is talking about.

 

I use a fatter pull cord in the desert (8mm) because ropes love getting stuck out here

Hola amigos. Que pasa with you?

 

So whats the best knot for tieing a static 6mm pull cord to a 10mm dynamic rope?

 

Also....

 

Can anyone see any negatives to a 6mm Polyester Pull Cord?

 

Imlay 6mm Pull Cord

 

Absorbs way less water and polyester is more static than nylon. 4lb 1oz and $75.
