4-Point Hanger (Rarely used)
While you can extend the ideas shown in the 3-Point Hanger section above, if you find yourself in this situation, consider using two separate up lines with 2-Point Hangers. There could conceiveably be times when a 4-Point might helpful, but they woudl be rare.
That said, here is an example of how you could do it:
Locking off with a Somerville Bowline
Here we have a chest harness.
We want to connect to both the upper and lower straps, on both sides of the stem.
This can be done using the Single Column approach.
On the first wrap, run the bight under the two straps on one side of the stem.
Then on the second wrap, run it under the two straps on the other side of the stem.
If you are going to lock off with a Somerville Bowline, extend the bight.
Give yourself extra room, at least 12” (~30cm), you will use some of that up in the next step.
Now reach down to where the wraps pass between the straps on each side, and pull them up…
Pull them up to the level you want your hanger to be – some slack to do this will come from the tail and some form the bight – then arrange all the lines in order shown: Tail, middle of the first wrap of the Single Column, middle of the rope where it passes from one side to the other, middle of the second wrap of the Single Column, then bight.
Now first group the middle three sets of lines together…
…then add the tail and bight on top of them.
Now lock off with a Somerville Bowline. Bight goes across all the strands…
Tail makes a loop around the bight.
Bight goes through the same path as your fingers, under all those strands…
…through this path…
…then up through loop as usual for a Somerville Bowline.
Tighten firmly.
When doing a 3- or 4-Point hanger, I always lock off the bight, even when using a Somerville Bowline. This bight is quite long, so…
…I will use some of that extra rope up with a Half Hitch (this was long enough that I probably could have done a second Half Hitch)…
…then run the tail through the bight.
If the legs of your hanger are not even…
…you can adjust them.
This is what you want: Even tension to all points when the tail is at your intended angle.
This is ready to go to the hard point.
(Additional angle 1)
(Additional angle 2)
When the upline comes back down from the hard point, run it through this path.
To complete this part of the lift system.
…
Locking off with a carabiner
Run the lines just as shown above…
…but when using carabiners there is no need for an extended bight length. Leave it at the same height you want your hangers.
Pull out the middle of the wraps as shown above. Arrange each on your fingers in order.
Hook the bight on your fingers as well.
Then hook the carabiner though all those loops and around the tail. Either direction is fine. Here I am going in order from bight to tail.
…like this.
Changing angle. Make sure the tail is on the back side of the carabiner, away from the gate.
We now need to lock off the hanger.
Tighten the lock off firmly.
This tail is now ready to go to the hard point.
