Rock Climbing anchors don't have to be complicated. Here are the 3 anchors you should know for building anchors on 2 bolts:
1. Pre-Equalized
2. The Quad
3. Two Quickdraws
Principles to apply to your anchors:
a. Redundancy - requires more than one failure for the system to completely fail
b. Distribute the Load - divide up the force of the anchor onto the various components
c. Limit the Extension - avoid configurations where a failure would create a "shock load"
d. Angle of Legs - the angle of the legs of an anchor should generally be less than 60 degrees to limit force vectoring
Hello Internet. Today we're gonna make another anchor building video for you
the people of the Internet. Why don't you seem too excited? Alright we're gonna
make an anchor building video but this one's gonna be different. Roll the intro.
Hope you enjoyed that intro. That's our commute into this secret climbing area
that's totally on Mountain Project. Anchors! What do you need to know about
anchors? Let's see how many... Alright Luca, how many different terms do you think we
can come up with to describe the different principles of anchors?
Redundant. Equalized. Timely. Efficient. No extension. Limit the extension. Elegant.
Then what am I missing? I know there's more. Point system. Oh there's a... that's
right. Who the f*** does math when they're out like building anchors? So there's two
considerations that we should just really be on our list to double check
every time. The anchors are redundant and they distribute the load. Alright I've
said some words that I probably ought to explain. I've used the word redundant.
By redundant I mean that I have more than one component. These two legs are
separated or isolated by this knot. I've got two loops. I've got two carabiners. So if
you gave me a figurative or a real pair of scissors and I was allowed to cut
any one item here this anchor would not fail. It would still totally support the
system. A second thing is I've been saying distribute the load. Now these two
components are identical so in an ideal world we would just equalize the load
between them but it doesn't need to be perfect. Each of these is about ten times
stronger than it needs to be for the whole system and we've got two of them.
Let's dive right into the first anchor that we're gonna use as an example which
is a pre-equalized anchor. So for this example I'm just gonna click my
carabiners directly into the bolt hangers not further down the chain. A lot
of people ask does that matter where you clip to? The answer is no and yes. No it
doesn't really matter. It's all plenty strong but yes it does matter. You don't
want to clip somewhere that the carabiner is gonna get cross-loaded or
the gate is gonna be interacting with with the rock or another thing that
might actually push on that gate. And then since I'm building a pre-equalized
anchor I want to anticipate the direction it's gonna get loaded. Pull in
that direction, grab in the middle of the sling, and then tie my overhand or
figure-eight knot there. Load these guys up. So now you can see we've got a nice
clean equally distributed load amongst those two components. Alright next up the
quad. For the sake of of being different I'm actually gonna just clip into a
different part of the anchor here for this. Again the main thing is like those
gates are free, not pressing against anything. So I have a 180 centimeter
sling. Get it doubled over, tie the first knot. Sweet. I'll take this end, drop it
into its carabiner, unclip this end, bring it back down, get everything all
untwisted, tie my second knot. So in order to build my anchor now I want to clip
one carabiner to two of those strands and I want to clip the second carabiner
to the second two strands. See that they're completely separate from one
another. Drop that guy in there opposite and opposed and voila I've got an anchor.
Quads are an awesome application for two bolts. Pre-equalized anchors will work in
literally, virtually, completely. I really can't think of any scenario where you
couldn't build a pre-equalized anchor. But you've got to untie them or retie
them each time. Quads on the other hand, I could actually decide you know
actually I do want to clip it up here high. Oh maybe I only want one of them
high. It's still automatically distributing the load. Alright and for
our last example, in the words of every famous youtuber, I'm gonna tell you what
no one else will tell you. The two quick draws are perfectly legit. So for the
sake of experimentation I'm gonna go ahead and clip down here on the bottom
of these chains. There's a redundant anchor. Distributes the load. There's a
limited amount of extension. The angle is all good. It's simple. It's strong. Now let's
go back to where I clipped these. I clipped them in the bottom ring. So at
the point that I come back to clean this anchor, that's gonna be in the way. So I
really I would be better off if I didn't put them in the very bottom. But there
are some scenarios that we want to watch out for. In the event that your bolts
aren't at the same height and you don't have a variety of places to clip into on
the hardware, then yeah this isn't this isn't the way to go. You want to think
about pre-equalized or quad in that scenario. Alright let's close this video
out and get on with this. I don't know what it is with the fetish people have
on Instagram of posting every conceivable variation of anchors, but
just remember it doesn't have to be complicated. There's some really simple
ways of doing this that shouldn't be overwhelming. Cool. That's it. Until next time.
Back in the hole. See you guys later.
Don't worry. It's a squeeze tube. You can't fall out of a squeeze tube.
