Abstract: A wire rope vibration isolator includes a coil of wire rope having a predetermined number of individual consecutive coils, a first crimp bar, and a second crimp bar. Each of the crimp bars is essentially rectangular in shape and has a pair of opposing side surfaces. A series of lateral holes extending from one side surface to the other side surface of each of the bars is provided so that the predetermined number of individual consecutive coils may be threaded through the series of lateral holes of each of the bars.
