Not important on lead either, in my opinion. Any movement of the anchor point from the exact angle where the lode is equally distributed negates the matched carabiner alignment concern.

not important till someone dies then experts are all over it with their scientific data.

welcome to RC.com! People dont intend to help you, they just wreck whatever you say.
I don't believe that's true for the most part. It's just that in this forum, we jump pretty fast on bad/incorrect/unsafe answers and recommendations. The biggest problem are those who think they're experts after only a year or two of climbing, not realizing they know only marginally more than a pure beginner. There's one guy in particular recently who consistently gives bad advice in this forum.

The other issue are the beginners who are aggressively ignorant - the ones who ask a question then get all butthurt when a bunch of more experienced climbers give answers that are the opposite of what the beginner thought. Kindness towards that attitude is short lived.

I have no idea if you now agree with me or not. But my point was that if I were to come across a solid, two-bolt anchor I would happily clip a draw to each bolt and attach myself to it with a length of the climbing rope. Minute equalization via carabiner size would be of no consequence.









What does disturb me is the misspelling of "load".

Your anchor is too convoluted. If I saw that, I would not climb on it because it signals to me that you lack critical thinking skills and/or knowledge with regards to building anchors. It's probably safe, but I'm not sure I would describe it as "correct." If I were you, I would try to learn more from experienced climbers before trying to apply your anchoring knowledge in a real-world situation.

That's absurd. If that were the case then the bolts would also have to be just as exactly horizontally placed. That doesn't happen in practice. Close, sometimes, but not exact.

if the majeedinator actually climbed ... hed know that on good bolted belays, youd clip a draw anyways on one of the bolts to prevent a factor 2 ...

I still disagree with you due to fact that when you are trying to educate a beginner, it best to provide them with principles first than let them build their experience around it. telling a new climber that ohh yaa, just take two draws and clip it and you are good to go, sure it will do the job but you are not provide the whole thing.

if you ask most climbers why you clip in to two bolts instead of one, they all say " it safer" but only few know that every bolt adds as an extra safety factor and with two bolt it means, you still have 50% chance to live if one fails. three bolts cuts it down 67% if one fails.

IMO, that is an example of principle why we do things the certain way so two draws with mismatch carabiner length reduces the safety factor.

Sometimes I wonder why people give you so much shit. This is not one of those times.

You're not used to using the maths, are you?

Actually, I'm pretty sure you have a 100% chance of living if only one of the two bolts fail. Cool

No, actually it doesn't. And if anyone ever suggested to me that my anchor would be "safer" if I matched my carabiners to provide better equalization, I would simply step six inches to one side and say what if I just stood here instead? And if they said ok, now your anchor is safe, I think I'd be done climbing wih them.

Hello, Assuming the deck posts that the ropes are around are actually anchor with locking carabiners in them. Is this a safe and correct setup for a top anchor?

Thanks

Honestly, there is no way to tell if you have any idea what you are doing based on that nest of cord.

Here's what I propose: leave the deck alone, find a piece of rock, plug some gear or use natural anchors, create an anchor that you would actually use in the configuration you deem best, take a picture of all important components of the anchor (knots, 'biner orientation, protection, etc.), and then post it. Knowing what to do on deck posts means very little.

Can you get books on climbing and climbing anchors from a local library?
