Length: The maximum practical working length of this cord is 5 feet. Relaxed the coiled portion of this cord is about 14 inches long, NOT 9 FEET. Add a little more for the uncoiled portion on each end. It is called a 9 foot cord because 9 feet of material goes into the curling machine. This naming scheme is confusing but it's the standard.
