Crown Knot Used a component in a back splice and in the double crown knot. Can be used to temporarily prevent the ends of a laid rope from unraveling. Make a constriction around the rope about 7.5 cm 3 inches from the end. You can constrict it by tying a constrictor knot around the rope with a bit of twine, or you can tape it.
Unravel the end of the rope all the way to the constriction.
Bind the ends of the strands with tape to keep them from unraveling.
Double one strand (strand A) over itself and lay it between the other two (strands B and C), leaving a loop in its center.
Pull strand B over the end of strand A and lay it between strands A and C.
Pass strand C through the loop made in strand A.
Tighten all three strands carefully.
