PULLING THE CORD
The rope can then be pulled on the same side as the knot. Make sure the knots in the ends have been removed. Hold both ends of the rope until you absolutely must let go. If the rope becomes stuck, you can fix the other side to the anchor to ascend the stuck side, which is only possible when you have both ends. Be conscious of where the rope will fall when pulled. If the lead line becomes stuck, you need to either cut the rope or re-climb the pitch to get it unstuck. Some climbers use a thin dynamic rope to rappel with for this reason. Once the ropes are clear, begin setting the next rappel. Thread the ropes through the anchor and untie and retie the knot, setting up so you’re pulling the thin cord every time.
