Max travel height or the maximum hang length is determined by the Whisper-Flex manufacturer and is typically 600 feet. With ASME A17.1 Code changes for comp rope and cable to 5 to 1 instead of 4 to 1, some sizes of whisper-flex have been reduced to around 500 feet. ASME A17.1 restricts the use of whisper-flex to cars with a rated speed of 700 fpm. If you have further questions on whisper-flex, please write me back. I work for the manufacturer, Draka Elevator Products, Inc.
