NEED EXTENSION FOR TOASTMASTER COOL EDGE GRILL MODEL 896S

I'm assuming you mean the power cord. Most of these units use standard power cords. Take it to an appliance parts store to match it. If you can't find the cord you want, extension cords called heavy duty are available. Be sure that the power draw on the label on the cord equals or exceeds that of the unit. Some cords use 'amps'...some appliances use watts. To get amps from watts: take the wattage, divide by volts (typically 120) to get amps. A 1200 watt appliance uses 10 amps. Use the next highest rating.
