What do you think

two small plastic bottle cut in half , velcro inside one another. the first half bottle goes over the top rope and the second half goes under the second rope both cones facing out. you pull the rope and the cone allows ropes to fall smoother

Good idea

actually, even better, one piece flexible plastic flat with velcro when open but then when closed, it would be two cones back to back with proper diameter to hold the knot and tail. ( MS patent pending)

I assume that the 'cones' are covering the knot joining the two ropes togeather?

Hey, great idea. I'm gonna run right out and cut up some plastic bottles to carry around with me whenever I go climbing.

You might as well just wrap duct tape around the whole knot and tails.

I think the plastic bottles would get beat to hell too quickly to make it worthwhile, plus dying of humiliation from being seen with them dangling from my harness is not the way I want to go...

That said - That it gave you the idea for the covering made of a simpler material is worth having the idea. I would never buy such a thing, but....there are plenty who would, no doubt.

If you could make such a thing that would actually work, and not end up being just as liable to get stuck as knots, then you would probably have a viable product and could make millionssss...well, maybe a couple bucks.

Unless the bulky cone gets caught up on a branch or other cliff-side protrusion that a simple knot might otherwise easily be pulled through.

Ah, I see, I thought you might have been asking about a different amount of tail (please insert the smilely emoticon that I somehow can't bear to type).



As for rope tails, I prefer a bit more like 6-8 inches. No knot that I have ever tied has rolled, but for some reason 2-3 inches just doesn't allow me to feel safe.

I did consider mentioning that the pun was intended Wink

Even 6-8" should still fit in the bottles though, wouldn't it...?

Depending on the bottle size, I suppose that would be true enough.

But at the risk of jinxing a perfect record of never having a rope stuck when being pulled, and with the double-risk of sounding stupid...is the knot the primary culprit of stuck ropes?

If my admittedly weak memory serves me, it seems the only time I've had a rope get tangled was dropping the ropes while rapping. In those cases it stuck because it simply wrapped around something and wasn't going anywhere, knot of no knot.

Good question. Of the six times that come to mind, five were not because of the knot. One probably was but could not see the stickage point.

I use the EDK. May have saved some grief over the years. Perhaps Majid prefers the double fishermans?

I've had ropes stuck many times and it wasn't because of the knot getting hung up. it was because the rope fell into the crack or got hung up on something after it pulled through the anchor. Don't see how the bottle ends would have helped me much there.

I've climbed over 35 years at all the major areas in the US and a few in Canada. I have never once had a rope on a double rope rap get stuck and had to jug up to free it.

It's not the huge problem you think it is, and certainly not enough to make me want to carry more garbage on a climb.

Like Marc, I've got a lot of years in---53, but who's counting. I haven't been as lucky or as skillful though, in that time I've had four rappels I couldn't retrieve---at least not right away.

Two of them were raps that couldn't be pulled at all because of friction. One case, in a storm on Steeple Peak in the Wind Rivers, did require reascending the ropes and rerigging the rappel. In the other case, on the South Howser Tower in the Bugaboos, we yarded hard on the ropes and pulled the entire anchor off (yikes!).

In the other two cases, one on the descent from the Durrance Route on Devils Tower and the other on Solar Slab in Red Rock, the trailing rope hung up after coming free of the anchor.

In both cases, we were able to use the rope we had in hand to ascend and free the stuck rope. In both these cases, we would have been stranded if we had been using a thin tag line you can't lead on. The Devil's Tower situation would have been merely embarrassing, but the Solar Slab hang-up would have involved at least a bivouac in cold and very windy conditions and then depending on other parties to show up the next day to help---something that could conceivably not happen if the next day was stormy.

These experiences, widely-spaced as they were, convinced me to absolutely never use a tag line that couldn't be used as a lead rope in any place that was even a little remote. But once you are dragging a leadable tag line, you're better off with double half-ropes, which is what I settled on for many additional reasons.

I might add that in none of the situations I described was the knot the thing that jammed. Nonetheless, I believe that using a knot that is less prone to jamming (and also reduces the pulling effort required) is a sensible precaution.

As with any such precautions, one can overshoot the mark and head down the road to excessive and unwieldy procedures. I'd put the velcro'ed coke bottles in that category for me, but of course risk and safety are in the eye of the beholder.

I wasn't skill - it was all luck, especially in two notable instances where it took some time and lots of rope flipping shenanigans.

However, I'm going to recant my earlier post about never having a rope get stuck. There was indeed one time that I had forgotten about where we would have had to reclimb the first two pitches of Dark Shadows (Red Rocks, NV) if another party hadn't been descending after us.

You can get to the ground in a single rap from the top of P2 with double ropes. I forget the exact anchors, but there were some kind of chains and quicklinks involved. On the pulldown, because of the location of the links and the knobs of rock, just before the end slid through the anchor, somehow merely a loop - not a knot - formed in the last few inches of the rope and firmly wedged between the links and the rock. Three of us standing well out from the wall were unable to free it. Obviously though, this had nothing to do with the knot joining the two ropes.

Not so funny then---the block the slings were around came off and missed hitting us by a few feet.

When two people are yarding on one end and the other end is some how fixed, the pulley effect could subject the rap anchor to as much as four times the at least double body weight forces we were applying. You would hope your anchor was up to that, but this one evidently was not.

P.S. It was a "fixed" anchor with many slings on it from previous descents.
