Avoid
A knot normally tied on a bight. It has two loops, and can be used as a bunny ears knot, and would work for a Y-hang, or can have the tails pulled apart, and used as part of a traverse line. However, the length of the loops is quite difficult to adjust, and the knot is very difficult to set. Cross loading or just pulling on a tail can easily cause the knot to capsize into a variety of different configurations, which can cause the lengths of the loops and the rope to change quite dramatically, even if it has been set tightly. This knot is not stable enough to be used reliably, and it should be avoided. This knot could be confused with the double lineman's loop and double Alpine butterfly variation 3, since they are all called by the same name.
