Weber GENESIS 400 Griddle Insert lets you easily convert your Weber grill into a versatile griddle, for cooking smashed burgers, bacon, eggs, fajitas, and stir-fries. Crafted from carbon steel, this rust-resistant griddle insert is hardened under extreme heat and pressure to create a durable surface that resists moisture and rust. It comes pre-seasoned with food-safe oils, providing a natural, easy-release cooking surface that’s ready to use right out of the box. Unlike coated griddles, it’s safe to use with metal tools. The rear grease slot efficiently directs grease into your grill’s grease management system for easy cleanup. Designed to fit 4-burner Genesis grills from 2016 and later, this griddle insert combines convenience and performance for a superior grilling experience. Model Number: 6789
