My wrench/Whipple tether and anchor setups

Re: Can we just call it oceans\' tether?

...it made me laugh, too!

Thanks for posting, Robert. I like the base anchor system. looks like it would pass the 'whistle' test. I often use a Gri-Gri, and I've got into the habit of trying to set up the base anchor on an adjacent tree to attain a nice rope angle away from the stem. I think it's nice to keep the lowering device open for easier use, and less chance to be pinned against the stem.
 
Re: Can we just call it oceans\' tether?

A better choice for a ground anchor belay would be a Rig or I'd. They're rated for two-person loads and have auto-lock features.

Using a Gri-Gri safely isn't as easy and intuitive as they seem.

You are correct, Tom!

I have allowed my co-worker to employ a RADS for SRWP. It worked for him, and he would be the person to operate my base anchor. He is VERY familiar with the system and all its' components, otherwise I would have upgraded a long time ago.

I was thinking of updating the system in the very near future to a friction hitch/F8 combination as described in Donny's SRT manual. I feel it may be a bit more intuitive for anyone, and I like that the system is redundant, whereas a Rig or I'd alone would not be.
 
Re: Can we just call it oceans\' tether?

The I'D is rated for single person loads the RIG is rate for two person loads., or 250kg I believe.

petzl's problem with the Gri-Gri is mounting it to a structure. Not meant to be used that way, never really tested for it. The handle is a bit weak in that situation as well.

Just some clarification.

Rather than using an F8 consider using a rack. The rope flows much smoother and hockles a lot less. You can weave in much more friction even with a four bar rack. The friction is smooth too...not jumpy like with an eight. The belayer...and listen to my words...can ALMOST...let the rope free flow. The catch is that if the climber/victim starts to accelerate it can be a challenge to slow them down. Hence...almost ;)

F8's have many limitations. There are many other friction tools that generate more friction dependably and intuitively than eights.

Over the years I've been really surprised that arbos haven't widened their vision to using some of these other tools.
 
What's the deal with the Trango Cinch? I was under the impression that it was rated for a belay device attached to an anchor. Not sure of the load rating, though.

I thought you'd all get a laugh out of the Whipple stiffy thing! :b

Eric the tether works awesome with the hitchclimber pulley, it's very smooth, bro!

Yoyoman, don't mention it! I'm just trying to give back when I can, it's my passion! :)

And the rig, like yall said said, it's rated nicely and it can be used independently (as in a basal anchor), which the gri gri is supposed to be used attached to the person as a belay! I liked how it was used in comps and Derrick Martin is a big fan of it and uses it alot and i'm a big fan of him! :)
