Just curious what type of rack insert that is. Also is that the RT-340 grill you’re using?
Those are two RecTec "small interior shelves" on an RT-590.
They are good quality and fit in the dishwasher so cleanup is easy. Problem is the stuff on the bottom cooks faster and you have to remove the shelves to get it out because the legs are in the way. And they are on the expensive side if you get 2-3 of them. I wish RecTec had pull out racks, or at least side mounted ones.
