Bad ways to rig anchors... a continuing series.

[ratagonia]

This is what I call the Minnesota Clip, though BDC might have another name for it. Bad juju. If one bolt fails, basically the whole system goes. The rigging thus decreases the reliability of the system.



Don't do this! Found a few of these last run through Imlay.

If you did an overhand knot above the ring, would it make it ok?

[ratagonia]

Yes, that would be the "standard rigging", which is often the best way to rig it.

The ones in Imlay used short pieces of webbing, so they could not be tied up. I replaced them with longer pieces of webbing and tied them up.

Thanks Tom.

Since we are talking poor rigging, I have seen a few of these in Zion lately.



Better known as the American Death Triangle.

The danger of the American Death Triangle is highly exaggerated. To be covered at length on another occasion...

one simple twist is all the minnesota clip needs to at least assure that if one bolt fails the other has a chance of catching it. the drawback is that if one bolt does fail the drop onto the other bolt can shockload the remaining anchor. the distance of the drop is dependent on the length of the webbing between the rapide and the bolt.







the drop can me mitigated by adding an overhand knot .

As with anything there are many factors to consider. The quality of the anchors and length of the webbing are main factors. Anyway, I hope you are not insinuating it is okay to use? You are better off just anchoring to one of the bolts instead of two in this configuration.

Oh OH OH! I got one from this weekend, I titled this "where is the bolt kit when you need it?" you'll hear me yell "woo" at the end because we learn the water is deep enough to bypass it. :)

kinda sorta.

I find understanding is more useful than rules.

As I said, more to come at a later date. It is not a simple matter. Rarely would it be preferable to just use one of the bolts.

Where?

And, what was wrong with the anchor? Could not really see from the view provided.

I'm guessing it's the one mentioned here:

If a dead man anchor is built and everyone gets down it then that makes it close enough to being a good anchor in my book

Correct! We used Iceaxe's awesome beta and dropped in the top portion also. Wayyy better way to go IMO. Good thread.
