Jumars on dynamic rope
Jumars on dynamic rope
So I may need to do some jumaring up a fixed line, and I really don't want to go buy a static rope, so I'm wondering if the teeth on the jumar will damage my dynamic rope in any way. Of course, I'd still like to use my dynamic rope for climbing, but if using the jumars makes it unsafe then i'll have to find another method. I'll be using the single jumar/ grigri method and will probably only make a couple trips up and down the rope.

no damage
If you give a man a match, he'll be warm for a minute. If you set him on fire, he'll be warm for the rest of his life!
Re: Jumars on dynamic rope
I've been using my old dynamic ropes for the same purposes and have seen no damage. I have even gone ahead and TR'd as well as lead on the same ropes. And fallen. But like any piece of equipment, inspect it often and don't use it if you suspect or detect anything out of the ordinary.
Pick myself up, stop lookin' back.

Re: Jumars on dynamic rope
Aid climbers jug dynamic lead lines on every pitch of a route. The only thing you really need to watch is dynamic lines will abrade faster (as compared with static) when repeatedly moved up and down over a lip/edge/whatever. Therefore you need to be more careful about padding edges over which your rope may run when jugging. Also, it is slightly harder to jug a dynamic line because you lose more of your momentum to the "bounce" of the line.

Re: Jumars on dynamic rope
The only thing I have noticed is that a dynamic line looses some of it's stretch if you jug it ALOT.
because i can

Aren't the "teeth" on a Jumar about the same as a Gri-Gri?
Re: Jumars on dynamic rope
well, it's the same action where a metal cam pinches the rope, but the jumars have small teeth on the cam that bite into the rope's sheath to prevent slipping
