When I first assembled my Griddle/Grill and saw the foil liner for the grease catcher I was a little concerned that they would be hard to find. I was very happy to see that they weren't and that they weren't very expensive either.
As another reviewer stated this product does not fit Model 1842 rear drip pan. Model 1842 is a 22" griddle and the drip pan is only 7" not 8". Wish it fit my unit.
Well, they probably work ok in the larger griddles, but in the redesigned grease cup for the 17 and 22 inch models you have to bend fit them. That's ok when empty, but when full it makes a mess trying to get them out for disposal.
