Descend by self-lowering

This post discusses techniques and methods used in vertical rope work. If you do them wrong, you could die. Always practice vertical rope techniques under the supervision of an experienced climber, and ideally in a progression: from flat ground, to staircase, to vertical close to the ground before you ever try them in a real climbing situation.
We typically think of rappelling (or maybe being lowered by your partner) as the only options to get down a cliff. But there’s another one to consider: lowering yourself.
This technique is less common, and has a few pros and cons. You go more slowly and have increased friction, but there are times when those might be good!
It’s pretty simple.
Pass one end of the rope through the anchor.
Tie in to this end of the rope.
Put the other side of the rope into your rappel device.
Lower yourself.
Here's how to set it up with a standard tube style rappel device. Note extension and third hand back up,
Notes, pros & cons of self lowering . . .
For a self lower, be absolutely sure the rope is going through some kind of METAL connection (carabiner, quicklink, chain, rap ring, etc) at the anchor point, never webbing or cord! The rope is MOVING through the anchor point when you lower yourself!
You’re lowering on a single strand, which usually means less friction. But the rope is also moving through the anchor point, which adds friction. These sort of balance out, and your descent speed typically is about what it would be with a two strand rappel.
You’re descending at half speed compared to a standard rappel, which can help with rope control, again good if you have a skinny rope. Or, it could be a bummer if you have a long way to go.
The person who’s self lowering must deal with the entire length of the extra rope. (If your partner is lowering you, the extra rope stays at the upper anchor.) If you can get a good rope toss to make sure it gets down the cliff without tangling, good for you. If not, having the rope in a ropebag or backpack can make life a lot easier.
Be sure and tie a knot in the end of the rope (or maybe clip the other end of the rope to your belay loop with a locking carabiner) to close the rope system, so there’s no chance you can rap off of the end.
