In reply to henwardian:

Well the anchor was at right at the top but there wasn't a lot of room up there (was on leigh tor, Dartmoor) so I led it, topped out, then climbed back down a little bit. There was a ledge just under so stood on that, fixed myself to the crab which was now at head height and belayed from there.
I thought you were meant to have the crab from your anchor over the edge to reduce rope abrasion and avoid having the crab on an edge (where it could snap)?
