Rope Wrench and DRT?

Recommended Posts

After some advice regarding the ISC Rope Wrench device....  I climb using DRT all the time. I ether used a Petzl ZigZag (With  Petzl Karabiners) or the DMM Hitch Climber (With DMM Ultra O Karabiners).

Having never seen a ISC Rope Wrench device in real life.. I have only seen it used with the DMM Hitch Climber device on youtube... in Both SRT & DRT.... But they don't say what it is actually doing for them.

Question 1) I was therefore wondering what the benefit would be of adding a ISC Rope Wrench device to a DMM Hitch Climber device system in DRT climbing? ....

Question 2) I also understand that there is different set ups of the ISC Rope Wrench device... So which one would I need when climbing in DRT with a DMM Hitch Climber device?


Question 3) Or is there a better system ISC system to use instead of the hitch climber device when climbing in DRT?

All advice welcome..

It would be of absolutely no use what so ever DdRT climbing , zero!! Don’t even contemplate it unless you plan on using it for SRT.

Thanks for the reply.....

What is the key idea of it in SRT? Is it to just tend the knot up the line and to help reduce the knot from locking up tight on the rope by reducing the load on the knot due to applying friction.

Aye spot on with your second reason ...To help the knot from binding up and burning out cordage, the top pin and pulley or pin on older models takes some of the weight and acts like the other end of your double rope.. with out it the hitch would bind and burn out very quickly , try setting up a single line and a hitch at about 10 ft and bailing out and you will see how gnarly it is !
