These 10' cords are for use with the AC Infinity Control Outlets and 69 Pro controller.
Use the male to male replacement cord to connect the Pro 69 controller to other devices. Note the AC Infinity control outlets each include one of these cords already.
Use the male to female extension cord if you need to locate a control outle more than 10' away from the Pro 69 controller. Just connect this to the device's male to male connector. Up to 5 of these extension cords can be added together.
