We bought a few anchor sets a whiles ago and after putting in some bolts and an anchor the rest were left in the competent and thankful hands of the Ak-dong Climbing Club (round Yongseo Pokpo area). This is where I got them:
and the anchors were 2 bolt fixe chined anchors whose bolts are to be placed VERTICALLY rather than horizontally. The chain joining them is thus able (when correctly spaced) to share the load and also prevent shock-loading if one bolt did pop (the lower bolt hanger has a rap ring attached, but there is still plenty of room to pop in a draw on each bolt hanger to use instead (as you should) when top roping.
Newbies and some oldies might wonder :
WHY USE YOUR DRAWS TO TOP ROPE WHEN A RAP RING/ HOOK IS THERE??
Because everyone using that ring/ hook quickly wears it out and cuts it in half!! It really does happen. TR-ing wears out rings way way more than rappelling...and as you want the anchors to be bomber for everyone, it saves a lot of wear and tear on the anchor if you use your own (2) draws.
Whatever anchor we go with, permission and a sense of treading carefully about the stupidity/ unacceptability of death triangles will be important. We don't want to offend/ come across as smart-arse know it alls teaching the locals what is right and wrong. That would be counter-productive. YET Dom (et. al.) is 100% correct in that we should take an active role in helping rid the ROK of poor anchors. Alec(Cali4nia) also was very much into this idea.
We had a few dodgy anchors this week in Daedunsan, so you can count me in as well.
