personal "anchor chain" for Equalizing anchor?
|
I've used both the Sterling Chain Reactor and Metolius PAS as a personal "leash" for connecting to an anchor while setting up rappel or top-rope -- some people like to call these "anchor chains". But now I'm seeing some manufacturers claiming that I could also use it in constructing a 2-point |
|
I do it with bolts, sometimes I'll use it for a quick seconding rig for ice, but haven't done it with trad gear. Usually rope or cord. |
|
They sell 2 different products. |
|
Yes, and they claim that both products could be useful for making Equalizing anchors. Tristan B wrote:They sell 2 different products. PAS - metoliusclimbing.com/pas_pe… Anchor Chain - metoliusclimbing.com/anchor… |

Stirling Chain Reactor also comes in a Pro version, with the long loop on one end as a double sling. So while we're touching on multiple product models ... |
|
Nope, I don't own either. But those both pretty expensive. Just use draws or slings. I have a long draw with a locker on each side that I use for TR's and then just a normal draw on the other bolt. |

As Metolious say, they are for equalising anchors NOT dynamically equalising. They will never provide any dynamic equalisation unless you clip them tight between the two anchor points. |
|
If you were to clip only one of the loops, then your system wouldn't be redundant (loop cuts and you're done). While I realize this is highly unlikely, I thought I should point it out. |
|
The thing I don't like about it is you're clipped to one loop so there's no redundancy. I guess you could clip 2 separate loops but I think that would get cluttered/tangled quick. Maybe I'm misunderstanding how it's used. |
|
I'm not an expert on anchors, but I thought the usual concern for redundancy was that one of the protection points might fail. |

I have a question about attaching yourself to an anchor- I never even knew these Personal Anchor Systems existed until recently, but the way I have always connected myself to anchors has been by two dyneema slings either girth hitched or threaded (depending on how much length I need) through both belay loops and connected to the anchor with non locking carabiners. Is this unsafe? |

Is this unsafe?No, not at all unsafe. Though I would probably use lockers for anything other than cleaning sport anchors. |

When setting up a top rope on two bolts I prefer to use cord or rope as it has a sheath that was designed for abrasion resistance. The webbing found on the sterling chain reactor and other personal anchor systems "PAS" do not have a sheath. Pony up the extra few bucks and get some cord or rope. |

It kind of seems like reinventing the wheel. |

Say I do tie in with 2 slings, how on earth am I possibly going to drop the rope if it is still tied to my harness???? Or if you are talking about cleaning the pitch how do you anchor yourself with the rope and still manage to thread the chains and set it up for rappel? Also, are you high? |

For most sport anchors I tie in with the rope (to always stay on belay) and just to make myself happy I'll probably also initially clip in with a sling and locker. I have a PAS and I use it from time to time as it's nice to make the quick length adjustments, but really I barely use it. IMO I'd rather bring something for an anchor that I can use for other things: Cordelette, double length runner with 3 lockers, quick draws or I have two QD's set up with 4 small lockers. That last one is probably what I use on single pitch anchors the most when its an up and down shot. I honestly can't remember the last time I even brought my PAS out. Oh and just a thought, instead of two slings to tie in IMO always use the rope as one tie in point. That way you NEVER drop the rope. haha it would SUCK being safely tied into anchors with no rope.The PAS concent was designed and implemented to get novice climbers away from improperly using daisy chains. This marketing has worked well. It also allows climbers to easily extend their rappel devices making room for a back up prusik tied to the leg loop that won't get near the rappel device. |

Also, are you high?Specifically cleaning anchors, when you thread the anchors. It's a little hard to verbally explain so if anyone wants to correct me jump in. When I first get the top I tie in with my girth hitched sling and locker. Next I'll pull up a length of rope (enough to thread 4ft or so) and tie a eight in a bight, run the rope through one of the anchor biners, and attach the bight eight to my belay loop via locker. Now I'm tied in with a sling and the rope. Now I can undo the eight on my harness and thread that extra 4 or so feet through the anchor and retie in to my harness. Once I've tied back in, I can unclip the bight and undo the backup eight. I keep tension on my sling and have the belayer take up the extra 4 feet of slack in the rope. Finish taking down the anchor, weight the rope and give it a test, unclip the girthed sling and lower. This way you are always tied into the rope, always on belay and can't drop the rope. Hope that makes sense. It might sound complex in writting, but it's actually quick and easy. As far a multi-pitch, I'll have a girthed sling on my harness, but I typically tie in with a clove hitch on the rope. Quick to tie (even one handed), easily adjustable and dynamic. And no...not high. It's early at work and I'm tired, but apparently rambling enough for you to think I'm stoned. It's actually a pretty common and safe technique. ESPECIALLY when your'e wicked high. |

I have a PAS that I use to anchor in when cleaning single pitch sport climbs. Looking back, a single sling would do the trick but I bought a PAS early in my climbing career and figure I might as well use it. |

I guess that concern is because I don't have full control over those points. If it's a trad anchor, then I'm always sort of "making do" with whatever rock features I happen to find around my chose anchor location. If it's a bolt anchor, then I don't know the history of each bolt and I can't look "inside" the rock to verify the connection of the threads. But with pieces of gear I brought along myself, I do know the history of each single piece, and to some extent I can visually verify its current fitness (e.g. check nylon for fraying, carabiner metal for fatigue cracks). So for myself personally, I trust my life to a single piece of my own well-chosen well-cared-for gear all the time. Like every time I rappel I trust my life to a single loop of nylon fibers (my belay loop) and a single piece of metal (locking carabiner). So from my perspective, how is trusting a single (well-selected) nylon loop of my Sterling Chain reactor when constructing a belay anchor so different from my trusting a single nylon loop when rappeling? KenYou make a good point about the comparison with a belay loop, I think the difference is that I can continually inspect/protect my belay loop and rap device (also belay loops are actually two loops of webbing sewn together, have a look, you should see two layers). When that anchor is up there, and I'm top roping on it, it's usually either hard or impossible to see. A little abrasion on some sharp rock could potentially cut that loop. Redundancy, from what I've been taught and learned from experience, applies to all parts of the anchor. The success of your anchor shouldn't depend on any single piece of equipment. You use 2 bolts so that you have a back up in case one fails, it still holds, and that continues to the power point. For example, if you have 2 bolts and use two quick draws to clip your rope in, any single part of that anchor can fail and you might not even notice it from the ground. I see people top roping on one bolt, or one locker and they are usually fine, but I need a higher margin of safety. |

ESPECIALLY when your'e wicked high.riiiight I know all of the above. But you do realize its generally considered bad form to lower off sport climbs? In places like the Red River Gorge its pretty common because the climbs are so steep they are a real pain in the ass to clean on rappel. But how many climbs are there like that in Boulder? Generally its better to rappel, so my question was how do you always stay tied in to do that? |
