It is just an aluminum pan. I would love the drip pan from SnS, but at $90, plus a whole ton extra to ship it here (Canada), it is not a reasonable purchase.
Grant,
Thanks for that pic. Giving me ideas for my 26.
You might try a disposable turkey tray. It may cover the space a bit better. You can form them a bit too. I use them in my Bubba Keg, lined with foil, so I can use them for a good number of cooks.
I use all sorts of different pans etc...that pic just happened to be a small one I had in there as I had recently just cooked a small port roast over it...but yes, the 2/3 (roughly) space with the coals like that allow for a full size turkey tray too if needed.
