Bolt Hangers:
Q:
"I'm
interested in doing some anchor replacements at my local climbing area.
Can you guys give me some suggestions?"
A:
Good
to hear you're keeping up-to-date on the anchor replacement. Stainless
is the only way to go (vs. carbon steel anyway)! I just had a look in
the Rawl Fastening Systems Design Manual (2nd edition). Under
Mechanical Anchors, I looked up the Power Bolt (I think this is what
you're referring to as the 5 piece). In stainless 1/2" dia., I see
lengths of - 2 1/2", 3", 5" (embedded depths) all of which torque to 35
ft./lbs. In tension, they are rated to - 5,935, 7325, 8,060
(lbf.) in shear - 9,455, 10,150, 12,930 (lbf.). These numbers are for
2000 psi concrete - they get better in higher strength concretes/rock
types. The numbers also indicate ultimate loads (failure of part). The
extra length does give significant strength advantages! Rawl also makes
the Power Stud - which is similar to the Fixe (threaded shaft w/nut
head) in 1/2" stainless steel - lengths are 2 3/4", 3 3/4", 4 1/2", 5
1/2". I generally buy whatever I can get a screaming deal on!
It's worth calling around to a bunch of fastener suppliers - oftentimes,
they will over-buy and you can get really good deals. I found a load of
3/8" s.s. hilti bolts a few years ago and got them for a little over
$1.00 /ea. If you know any contractors, they may personally know the
Rawl sales rep in your area - can get deals that way as well. I
generally don't tell them I'm using the anchors for rock climbing - it
makes them nervous! Try phoning 914-235-6300 and see if you can get a
catalog - (number 0017 - 2nd edt - <may be a new edt. out now.>) Lots
of good info. Hilti has a similar line of products - Kwik Bolt etc. -
Customer service # 1-800-879-8000 or www.us.hilti.com - good luck with
the project.
Harnesses:
Q:
I am
looking for a women's harness and I saw your newest model at my local
shop. I tried it on and it fit well, but I was concerned that
there didn't seem to be a quick rear drop system for the leg
loops. How am I supposed to pee without taking the whole thing
off?
A:
Thanks for taking the time to write with your harness question. I assume
you are asking about the Safe Tech Women's Deluxe, so my answer will be
specific to that model. You are basically correct; the leg loops do not
drop easily. We made this compromise in order to make the leg loop strap
strong enough to hold you in the event that it somehow gets clipped into
and then loaded. I assume you read the packaging that accompanied the
harness, so you are familiar with the philosophy behind the Safe Tech
harnesses. It may seem like we're going too far with the leg loop strap,
but I heard a story recently that convinced me otherwise.
A
party of 3 very experienced climbers was on El Cap trying to run 2
pitches together to save time. Unfortunately, the rope ran out before
the leader could reach a belay. The only solution was for the second to
dismantle the lower belay and simul-climb. Normally this wouldn't be
that big a deal. Unfortunately, the third climber was supposed to climb
on the second rope that was being trailed by the leader. Ordinarily,
this rope would be in the leader's rear haul loop, but in her haste, the
leader had mistakenly missed the haul loop and clipped into her leg loop
strap. If the third had fallen, it would have been certain death.
Luckily no one fell and a tragedy was narrowly averted. However, with a
rear leg loop strap capable of holding 1500lbf, even if the third had
fallen, he would have had a chance. No guarantee, but better than
nothing.
That
is what the Safe Tech harnesses are all about - giving you a second
chance when a mistake happens. You may think that you would never make a
mistake like the one I just described, but that is exactly how most
accidents go. Someone makes a mistake that is virtually inconceivable.
Anyway, that's the Safe Tech sales pitch. To get back to your question:
I am hardly an expert on these matters, but all of the female climbing
partners I've had have kept their leg loops on when answering
nature's call. They wriggle their trousers down, squat, and then use the
stretch in the leg loop strap to get the whole business down low enough
to be out of the line of fire. It seems faster and more convenient
than leg loop disassembly. I apologize if my description was vulgar, but
it was the best I could do. Anyway, this is the feedback we have
received from women climbers when designing the new harnesses and it
certainly played into our decision to sacrifice the drop seat for the
additional security.
I
hope that helps you make your harness decision. Thanks for checking our
harness out and taking the time to ask the question before you
purchased.
Response:
Thanks for the
return e-mail. FYI-- I went back to the shop (Neptune in Boulder) and
retried on the harness. The stretch in the leg straps let me get the leg
loops out of the way when I experimented with dropping my pants. So
besides buying the harness, I informed the sales people of this feature.
Thanks for the Beta. Carol
