I'm guessing they are tying the figure eights as a backup on the end of the rope that is the tag end, hooking the ropeman/prusik biner in that loop in case the biner or ropeman were to fail. It's a redundancy thing. But I could be wrong, that just makes sense to me.
If you want to do what you mention above in original post, and what they may be describing in the posts above, just add another prusik knot. Or if using a ropeman, use the prusik that comes with the ropes. Thats the whole reason for the spliced eyes, so you reduce the bulk that the figure 8 knot makes.
that's why he's asking if there are spliced eyes on both ends.
LOL...you get it
I get it to. Maybe you're not understanding what Im trying to say. Have you considered that when tying a backup to the end of your tethr, depending on tethr length, you could have a significant drop before the tethr would catch? Adding to the forces put on the rope. With a prusik tied as a back up, you can adjust it after being tied in, to give yourself enough room to manuever, but still limit the amount of drop IF something was to fail.
I understand very clearly all your post in this thread. I do not disagree with anything you have said. Everything you have said is correct and are viable options. I would rather use a prusik/swabish for a backup than tie a figure 8.
Right, but by doing it this way your allowing yourself to a shock load fall of a couple feet if your ropeman fails. If you back it up with a prusik then you will only drop a couple inches at most. Then as a final precaution there should be a stopper knot of your choosing (I like the double fisherman) so that if for some reason both fail you are stopped at the end of the tether by that. If you going to put a redundency failsafe in why would you do it at the end of the tether and potentially expose yourself to a shock when you could just use a prusik and avoid the possibility. Shock fails of even 2 feet can be extremely violent and cause serious injuries. Your best to have a failsafe set up for the shortest possible fall (prusik just above ropeman) then longest possible fall (end of your tether).
This is what I said before. I run a Prusik actually below my ropeman and clip it with a carabiner to my lineman’s loop. Making sure to keep as little slack in it as possible. Gives me all the freedom I need to move and also backs up any possible failure of not only the ropeman but also bridge.
That’s great however, buy putting your prusik below the ropeman you have to potential for the prusik to not work. If you ropeman does fail and is able to slide your tether rope while clipped into the carabiner then the ropeman will act as an auto adjusting device and prevent the prusik from gripping the tether by pushing it down the same way a micro pulley or an auto adjuster does on a linesman. Anytime you have a device the safety compression knot that you are using to “back up” that device should be above the device. Otherwise as I said before you have the potential of the device to push the prusik down the rope during the fall rendering the prusik useless.
Great advice, never knew that could happen. Used to run it above then thought, below and to the lineman loop was killing two birds one stone so to speak. Didn’t know that it could push the Prusik down without it engaging. I will switch back. Thanks for the knowledge.
