UL approved. Double lead cord. One for the power and the other for the foot pedal. Will fit many machines and sergers. Most kenmore free arm machines. 148, 158 and 358 series machines. Cord has 3 round prongs, 2 close together and 1 spaced apart.
It will be a nice to have this spare the next time I use one of the two Kenmore 158s and the cord currently on it, actually doesn't work. It helps to turn the machine on...Ha!
Sewing tired that evening.
