>>>>What is this "double jacket cable" mentioned by the firefighters who rescued the window cleaner?

The fire chief was quoted as saying, "His double jacket cable, the exterior jacket’s cable, had failed," but not the interior cable. <<<<

 

It is a type of rope that has two parts to it.  A braided core that provides the strength and an outer wrapping that protects and provides a more uniform and smooth surface.  It appears that the outer layer failed and jammed his rope grab or his descent control device.
