Let’s attach to three straps this time.

Run your new upline under each strap in sequence.

Pull primary bight through…

…far enough that you have some with which work.

Now pull the part of the rope between the closest two straps. Pull it up at least a handbreadth away from the body (more is also fine) to form a secondary bight.

Position the primary bight parallel to your new secondary bight.

Now pull up the rope between the next two straps to form another secondary bight.

Lay that new secondary bight on top of your fingers, next to the other lines already there.

Grab the tail.

Reverse its tension and lay it on top of your fingers next to the strands of the primary and secondary bights. The tail and bight should be running in opposite directions.

Just as with the 1-Point and 2-Point Hangers, this is the starting point for the Somerville Bowline. Gather all the strands together with the bight up away from them.

Complete the Somerville Bowline.

It should look like this. If the hanger does not put the same tension on each strand…

…you can pull the inner lines of the hangers to adjust.

Choose what you will do with the bight. (See “Options for the Bight” above).

Here I have chosen to use up the long bight with a Half Hitch…

… and then run the tail through the bight to keep it out of the way.

This line is now ready to be run up to the hard point.

Run your new upline under each strap in sequence. This time, you only need to pull the bight through to the level you want you hanger to be.

Make sure the gate of your carabiner is pointing down, then clip the carabiner to the rope in reverse order that you ran it: Through the primary bight, then…

… under the second mid-strap point, then…

…

… under the first mid-strap point, then…

...

… around the tail…

…

Run the tail over a point at the back of the carabiner, away from the gate.

Add an Overhand Knot or Half Hitch to lock the lines of the hanger together (as shown in the 1-Point Hanger section above). Here I am using the Overhand Knot method, which I prefer for multi-point hangers.

Tighten the lock off firmly.

This upline is now ready to be run up to the hard point.

If you need to adjust the length of the legs so that that pull on the different straps with even tension, you can do so by pulling on the inner lines of the hanger…

…

This even distribution of tension is what you are looking for.

To create your lift systems, run your upline to the hard point, then down through the carabiner…

…then back up to the hard point.
