Hey, I was thinking about applying the concept of the "Death GriGri Modification" for solo climbing, to a Trango Cinch.

Obviously the 2 devices are very different in parts aspect, for example, the GriGri uses a spring inside the cam, and it has 2 covers on the sides, the Cinch have none of this attributes.

So, before I wreck my Cinch, I was wondering if someone has done something similar that have worked.

Thanks...

Gang,
We can not, under any circumstances, recommend the Cinch for soloing, either TR or lead. We've done an enormous amount of testing on it, all to get it dialed for belaying and lowering rock climbers. We haven't spent one second testing it for soloing. So, if you do try it, AMFYOYO.

Here's the way my lawyer wants me to say the same thing...

The Cinch is not designed or approved for solo or self belaying under any circumstances. Using the Cinch in this manner can result in death and/or serious injury. The uses for the Cinch that are being discussed on this site have not been tested and are not approved uses. The Cinch was not designed as a self belay device and such improper use is potentially fatal. The Cinch is designed, sold, and approved for use only as illustrated in the pamphlet that the Cinch is sold with.



Use of the Cinch in any manner not illustrated in that pamphlet can result in death and/or serious injury. The user is responsible for learning the correct way to operate the Cinch and operating the Cinch correctly. The user is responsible for any and all death, injury and/or risks arising out of his or her use of the Cinch. If you do not accept this responsibility, do not use the Cinch. THE MANUFACTURER AND RESELLERS OF THE CINCH EXPLICITLY DISCLAIM ANY AND ALL RESPONSIBILITY AND LIABILITY FOR ANY DEATH, INJURY OR DAMAGE TO ANY PERSON OR PROPERTY THAT MAY OCCUR THAT IS RELATED TO THE USE OF THIS PRODUCT.

I don't, but what were you thinking to do to your cinch? If you look at the handle of each, you will quickly see that the gri gri would be superior as it is less likely to get accidentally opened.

Nop, it does not.

Im not looking for warnings, Im looking for Ideas that could complement my Idea.

And I’ve learned that using it properly might not include using it for roped soloing. AMGA guide Mark Beverly recently performed several dynamic drop tests on Cinches and other belay devices, and Cinches displayed surprising results. They broke.

However, and this is a big HOWEVER, I have some reservations about the way in which Beverly tested his Cinches. He attached one Cinch to the ground and one to an 80kg test load. He then full-on, UIAA-high-factor dropped that sucker and observed the aforementioned results. The problem is that Beverly also tied stopper knots right up next to both Cinches to completely eliminate the chance of rope slipping through the devices from either end. The Cinch, it turns out, is designed to allow slippage at 7kN. Deprived of its design-given right to relieve a few thousand Sir Isaacs, the test left 7kN in the dust and the Cinch attached to the load end of the system broke.

While it’s worth noting that every device Beverly tested was subjected to the exact same rigors and that only the Cinch broke under them, there is some debate over whether or not it’s fair to test a device in a way that specifically prohibits its intended function.

It is also worth noting that a stopper knot right next to the device and a device attached to a falling load – not a belayer – most closely resembles what one might rig for roped soling, hence my previous point. If you decide not to heed my and Trango's advice and you do use a Cinch for roped soloing, you must refrain from tying stopper knots within a few feet of the device. It must be allowed to relieve tension as designed.

Notice I reply a post previous yours saying that I found the way to do it, so your comment is just meaningless.
