#1 Flavor Savor. Most of us just use disposable aluminum loaf pans for liquid, snugged up against the smoke box. No washing required. Not sure if anyone uses this, especially with the #1, which is limited on space for hanging something like this from the racks. Not sure if it would be helpful for collecting drippings. Probably not in the #1.

#2 Rib Hooks. I got those too, free with my #1. The #1 isn't nearly tall enough to make those work, and even if you had a larger model, I don't know anyone who has used them. They are not necessary or particularly advantageous. I'm still looking for another clever idea for repurposing mine!
