Step 1
Fix the clips (cable pullers) onto the lines, and you can start to join the lines. Leave about 20 cm on both lines to make the knot.
Step 2
Make 3 loops with the first line around the second line, and leave about 20cm free on the second one to make the knot.
Step 3
Repeat the process with the other one. Finish rolling the line in the center of the knot. Release the rope tensioner.
Step 4
Final aspect of an end to end knot.
