At my son's suggestion, I purchased a Weber 2-head grill and i'm delighted with it. Then I remembered the drip pan and discovered an insert in it, which I washed out - then I thought there must be a better way. And these very inexpensive aluminum foil drip pans came fast from Amazon, and they're exactly perfect for the job. Once the grease builds up, just toss the pan and put in another, and you're ready to go.
Reasonably priced alternative to Weber brand foil drip pan liners. They seem comparable to the originals and function fine. My only concern was with the packaging as a few of the lot were damaged during shipping but I was able make use of them anyway.
These trays fit perfectly in the drip pan on my Weber Genesis 300 Series grill. I see a lot of people commenting about dimensions and there seems to be some confusion. There are two sets of measurements for the outside of the pan as the pan is slightly larger at the top. The bottom of the pan measures 7-1/2" x 5". The top of the pan measures 8-11/16" x 6-1/4". The depth of the pan is 1-1/8".
Bought these to avoid having to clean and scrub the steel drip pan included with my grill. Drop them into place in the steel pan, grill away, then toss them. Inexpensive and do a great job. Can use them several times before discarding.
