This drip tray is for the 1st generation Traeger Timberline 1300 model which is commonly denoted as the “AC” model. All 1st generation models have a power cord that is “hard-wired” into the hopper and cannot be unplugged from the grill itself.
If you have a power cord on your Timberline that can be removed from the jack under the hopper, you have the 2nd generation Timberline grill which is referred to as the “DC” model.
The DC Timberline 1300 uses drip tray part 0477.
