After working with the rope-grab + a friction device (the figure-8 and my new Petzl Pirana) and then going back to the Gri-Gri, I still prefer the Gri-Gri unless the roof is only moderately steep.
But I'm glad I worked out a solution for a controlled descent with rope-grab on a very steep roof. It's a personal decision and I think anyone working with Rope & Harness will evolve something they are comfortable with.
If a ground auger is not the way to tie off suggestions of what will work will be appreciated.
Hi Jim, actually that issue has been pretty "aired out" previously on this thread (and it may have been touched on during this other thread http://www.catadjuster.org/Forums/t...spx )
I have brought those augers with me but never had to use them. Seems there is always some very substantial hedge/bush to wrap webbing around the base. I personally believe a substantial bush is going to be anchored in the dirt a lot better than something I am going to superficially screw in the ground - and there always seems to be a decent bush.
Very often there is a deck with support posts (4x4's) accessible below the deck if no railing above it. I have been on some very deteriorated decks where I tied off to several places and did not rely on one tie-off point.
Don't forget about fencing, and that has been mentioned before. You can push webbing around the 4x4 there is always a place where the post deviates from the panels. Again, you can tie off to more than one post and run that webbing through the end of your rope. Webbing is fairly cheap, you will want to get pieces cut in various lengths.
I have tied off to my vehicle on rare occasion (only keys in my pocket) and have brought large water containers but never needed to fill them up.
Start visualizing where you would tie-off to on every house you walk up to this coming week, it won't be an issue anymore.
