This drip tray is for the 1st generation Traeger Timberline 850 model which is commonly denoted as the “AC” model Timberline 850. 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.
