The QUADRALETTE: a final solution?

Hi everybody,

Since 2006 I followed that long debate regarding anchors with sliding X, cordelette, equalette, quad and triplette. By mixing the best ideas provided by many of you, in particular asdf, trenchdigger and mhabitch, I worked out something based on the Quad power point, but with the advantage of using a self equalizing and perfect load distribution on 4 pro as proposed originaly by mhabitch. I would like to know what you think about that Quadralette.

The four arms might look a bit short on the picture as I used a 21ft rope. A 27ft would give a better range.

looks interesting. i think i will stick with the sliding x & cordelette.

Final solution to what?

The equallette was as complicated as it needed to get, and many times it's more complicated than it needs to be. Luckily, it's as versatile as it is potentially time-consuming. Occasionally I'll use it to rig pro. More often, I'll tie it off around a bigass tree, or tie it off short to clip two bolts on a high-traffic route. Probably my favorite anchor I've ever rigged was two 120cm slings over a 2ft. diameter rock horn. It was ready to go in about 10 seconds and more bomber than you could ever need...

Now you've gone and added rap-rings and other additional shit. More weight, more complication...

Let's be clear about something: The equallette is a few years old. It's nice in certain situations. I carry one with me on most climbs and love it.

But climbers were anchoring for decades before it showed up and coming home just fine. They had the horse in front of the cart because they understood that super-bomber gear placements came above EVERYTHING, and that no wizard-rigging would ever make up for poor placements.

With some of today's elaborate spider-webs, I wonder...

Keep it simple...if you don't need more than slings or the rope to rig the belay, then don't use more.

We need to get past this idea that in climbing there's a holy grail anchor system that works for everything. There isn't...and trying to achieve that actively undermines your safety acumen with the gear because you're more focused on "THE" method rather than the options and why some may be better than others.

First, what ja1484 said!
Second - How is its functionality in the real world different from an equallette? If one piece fails, you will get extension to the extent of the limiter knots in the central portion. Yes, your power point does have 2 load bearing strands plus 2 capturing strands, but that is really not the vulnerable point in anchor rigging. As long as you have redundancy (2 strands), you are good. In the recommended rigging of the cordellette, you have one biner on each strand...and one capture strand for each biner.

Carrying an extra 7 feet of cord, and extra rings adds up to bulk on my harness (actually, a bit more concern to me than weight). Uggh.

Bottom line for me is that, while interesting, it's not an improvement. However, keep experimenting.

I agree with you that no solution exist and we have to adapt to every anchor situation, The game of sliding X vs extention is like trying to solution the car's dilemma of performance vs economy. The equalette was not intended to become a do-it-all system. Like you, I always go with simplicity with trees, bolts, etc...

But the point with that Quadralette, it was intended to solve two problems encountered with the equalette i.e.
1- the master point witch require 2 to 3 biners (auto-lock mode) and its 1 load bearing strands and 1 capturing strands.
2-it's uncapability to equalize more than two pieces at a time.

I tought you were going to understand the context of its use but I do MEA CULPA in misleading the intention of the Quadralette in the title of the post.

I tried both Equalette and Quadralette on the field and they take the same time to set.

Multi-strand powerpoint equallettes are straightforward to tie.

Since when could equallettes only equalize two pieces?

wrong---use one locking biner for your [cinch, gri-gri, guide] using two strands with sliding x
In reply to:

huh?

---and for adding a 'shelf' to your equalette, tie another pair of limiting knots above the other two and clip in between on each side for your tie-in, then use the center for your direct/indirect belay for the second. done deal.

Great info!
There have been speculations as to how long it would take to wade through
all of that, and we're glad for this one datapoint: 3 years.
(But if it were technically possible, there are folks here who'd QUOTE the
entire thread and add one line, fer sure.)

In reply to:

In the worst-case scenario--i.e., 3 anchors failing--, you're on ONE
strand; that doesn't qualify one for the grand prize.

(That center part of your powerpoint triangle should not be of equal
length as the tensioned half (between limiter Overhand knots), but
more nearly half as long, limiting extension that much more.)

In reply to:

Nothing does, really; but what's magic about three?
The quad set-ups ideally start at 25% per anchor, and become
25-25-50 on a failure, or if employed one anchor short;
but even perfect 3-arm equalization of 33% needs anchors
able to hold 50-50 if one fails, so ... .

That paint can isn't going anywhere... what kind of screws did you use on the coat hanger? That's the real question.Wink

I think that we most definitely over complicate things... what happen to SRENE and "good enough"? I'm sure that anchor is truck but I don't think it's worth the effort, weight, time, and cluster... no offense of course, that's just too much for me.

Speaking of which...a AMGA certified climber (not climbing with my party) criticized my equalette off two bomber glue ins because of the extension and was adamant on having an figure 8 in the system which I said thank you, noted, and I am happy with my anchor.... any reason for him to be so forceful with his advice?

It was a TR anchor...I don't have access to my anchors book to look it up but I don't recall any advice not to use it as a TR anchor...

Well, of course you're supposed to use a quad off of two bolts, not an equallette - man were you risking things! Shocked

I suspect that he was not familiar with it. The AMGA "top rope site management course" I did recently emphasized the BHK (big honking knot) as the power point. Where did he want the figure eight? At the rope connection point, thus defeating the equalization?
Darn noobs! Tongue

Nope...at the power point. Oh well.. to each their own. Which, I happen to like my own. What bugged me was the shit don't stink mentality and that there is only one way to do it right in his eyes.

It was the same problem with the cordelette and the equalette. 3 pieces gone and you are left on 1 strand. Unless you use a 3 "V" configuration system with dynnema runners, how can you do different or better?

It was the same problem with the cordelette and the equalette. 3 pieces gone and you are left on 1 strand. Unless you use a 3 "V" configuration system with dyneema runners, how can you do different or better?
Your last question is the key insight to ask Why try to build this
quad anchor out of a single piece of gear?
--rather than using multiple pieces, which can (1) enable some to be
specialized for their particular function (e.g., getting slick HMPE slings
for the "sliding span"/"V", and semi-elastic, easily knottable cord for
the tied-to-anchor arms) and (2) more likely meet multiple tasks readily
(e.g., separate items can go to distinct places).

Tying off one HMPE sling with cord is a problem I think I've pretty well
solved: the knot is an Overhand tied through the bight-end of the sling,
and has identical loading from either side, and makes a good eyeknot
for the holding arm where the other fails. That does for >2< anchor points.

Now, going for 3-4 anchors entails a 2nd extension-limiting equalizing
triangle (closed "V") to join this first ELET structure to the additional arm(s).
Here, a single but maybe longer-than-24"(60cm) sling could be used,
either forming Clove hitches to each sliding 'biner (single-strand V),
or, clipping a bight-end to one side, moving across (closing, non-V side)
to tie a Clove to other 'biner, forming the "V", then finishing with a
Clove (IN, not with bight-end--single-strand) or Girth Hitch to 1st 'biner
(which should force the loose, first-clipped bight-end to move along
the strong axis, not gate-side
of that 'biner should that side's anchor
fail).

(As for the "cordelette" having a potential for loading a single strand,
I don't follow: to my mind, the c. is a non-equalizing anchor with bight
arms (i.e., 2 strands in each) joined in that BHK powerpoint.)

Nothing is magic about three. It's probably the most common number of pieces in a trad anchor so any gizmo that claims to be the "final solution" ought to be able to handle that number gracefully, as well as two, four, and more pieces. When you're in a situation that calls for one of these partially self-equalizing rigs it's not as if you can just add in another placement if what you've found isn't an even number.

Suppose all you get are a few questionable placements, there's no jesus nut in sight, it's non-trivial climbing off the belay, no way to relocate the belay to a better spot, and retreat is not a viable option. You'd best do what you can to spread the load over those junk pieces. It might not help if your partner falls onto the anchor. Then again, who knows, it might make all the difference.

But 50% ("ideally") of the load on one piece is pretty crappy. Not much better than a cordelette, maybe no better given the potential for extension.

It looks like it works well to keep that paint can from ripping those dowels.

A cordelette can be entirely non-distributing if the angle of loading shifts
and esp. w/highly inelastic cord. If you're with such sketchy placements,
then I'd advise really seeking out FOUR and thus getting in two ELETS
feeding the powerpoint ELET for max equalizing & distribution, nevermind
the trad three.

.:. I don't see the need to have a big focus on equalizing three,
based on traditional choice of that number: it is leading to many
too-clever-by-half solutions, which actually don't equalize so well,
and require a good deal of rehearsal in order to be competent to
use--something that doesn't bode well for situations w/stress.
