Weber 7004 SmokeFire Wet Smoke Kit, Silver

As advertised

I bought three of these, thinking that's how many I'd need to cover the majority of the grill when long/slow cooking. You actually need just one to go on top of the large middle heat shield. All other areas of the grill, you can simply lay a 2" high drip pan directly over the flavorizer bars.

A must have system for wet smoking and drip management. Keeps the pans from teetering on the center flavorizer. You only get 4 pans and a metal frame. Should only cost $10.

This is to be used over the burn pot cover in the center of the grill. Not necessary, as one could put drip pans or water pans directly on the flavorizor bars instead. Or on the grates and cook meat on the top shelf. The SmokeFire has a poor built-in grease management system, but mitigation with drip pans makes cleanup simple!

I have 2 kits on my EX4 and use them to catch grease & drippings during low & slow cooks. It makes cleanup simple. Installation is simple - they just sit in there, under the grates. Don't expect any space between the drip pan and the grates.
