If you are talking about the long crumb tray underneath, it slides onto narrow long metal strips on each side under the toaster, starting from the left short side as you are facing the toaster with the control buttons on the right long side. It's a bit like sliding a drawer into a dresser. Ours slides in and out easily. You might need to turn the toaster on it's side the first time to see the strips and slide the tray in. Just unplug the toaster first. Hope this helps.
