Weber 6789 Carbon Steel Griddle Insert

The Weber 6789 griddle insert is a pre-seasoned carbon-steel cooking surface designed to convert compatible Genesis grills to flat-top cooking. Its full-size design, rimmed edges and grease management integration suit foods that are awkward to cook on open grates, but compatibility is specific to Genesis and Genesis II 400 Series gas grills from 2016 onward.

What to know before buying

Listing details to confirm

Check that the grill is a Genesis or Genesis II 400 Series gas model from 2016 or newer before buying. The listing also says Genesis 4-burner models for 2016–2026, while the detailed description gives 2016 and newer, so the precise fit range and year coverage are not fully consistent. The 2-year warranty is a listing claim, and its terms are not provided. The storage bag is sold separately.
