Hi and welcome to FixYa, I am Kelly.
These cords (unless the magnetic type are available at most hardware stores ("Woods" / Woods Industries or Coleman Cable are the product brand names.) These cords are usually in the area of extension cords.
Having said that... The distance between the pins is the difference. There are 1/2" cords 11/16" plug cords and 1 1/16" cords. I need to know the distance between the pins center to center of your fryer connector terminals.
Most Fryers use a 3 Ft cord and roasters use a 6 ft Cord. You cna use a 6 ft cord but do NOT use it for an extended period. The cord you purchase must be wire gage 16/2 NOT 18/2 in wire size.
The 18/2 gage will only handle 1250 watts.
The part number of the cord will be either 0290 or 09326 (You can net "IMAGE search" these for sources)
Here is one source for the cord.
If you have the magnetic base / end plug let me know and I will find you the correct plug.
Just repsond here and say you need the magnetic recepticle cord.
Thanks for choosing FixYa,
