Stanbroil Stainless Steel Griddle Insert for Weber Genesis II 400-Series — 533 sq in Drop-In, Even-Heat Surface

Stanbroil's stainless steel griddle insert converts a Weber Genesis II 400-series grill into a spacious, corrosion-resistant flat-top cooking surface ideal for breakfast, sandwiches and seared mains.

This stainless-steel replacement griddle is designed specifically for Weber Genesis I & II four-burner 400-series models, giving you a reliable, easy-to-clean surface with 533 square inches of cooking area. Built to resist rust and high heat, the Stanbroil insert swaps in place of grates and flavorizer bars so you can expand your outdoor menu beyond direct-flame grilling to eggs, pancakes, teppanyaki-style dishes and delicate items that benefit from even contact heat.

Installation is a simple remove-and-replace: lift out grates and bars, then set the griddle into the same mounting points. It is also listed as a replacement option for Weber part 6789.

• Compatible with listed Weber Genesis I & II 4-burner 400-series models.
• Direct drop-in design — no tools required for basic installation.
• Works as an exact footprint substitute for factory griddle part 6789.

What cooking results can I expect from a stainless-steel griddle?

Stainless-steel delivers steady, responsive heat across the entire 533 sq. in. surface so foods cook evenly and develop consistent browning. It's excellent for breakfast foods, toasted sandwiches, seafood, vegetables and seared proteins that need full contact with a flat surface. Because it's reflow-resistant, you can push the griddle to high temperatures for searing or lower the heat for gentle cooking.

• Large 533 sq. in. area for multiple items at once—eggs, pancakes, steaks.
• Even heat distribution for consistent browning and searing.
• High-heat performance for quick sears or lower settings for delicate foods.

How simple is cleanup and maintenance?

Stainless steel is low-maintenance: food release improves with seasoning and most residues wipe away after cooling. The flat surface minimizes crevices where grease accumulates, so routine cleaning is just a scrape and wash. Periodic deep cleaning and re-seasoning will prolong the griddle's appearance and cooking performance.

• Flat stainless-steel surface wipes clean—less trapped debris.
• Dish soap and hot water or a gentle scraper handle most cleanup tasks.
• Occasional re-seasoning helps maintain nonstick performance over time.

Will this griddle stand up to heavy outdoor use?

Constructed from corrosion-resistant stainless steel, the insert resists rust and tolerates high grill temperatures, making it suitable for frequent tailgates, backyard barbecues and party cooking. Its durable build reduces the need for frequent replacements, providing a long-term upgrade for users who cook outdoors often. Always follow basic care — dry after washing and store covered when not in use — to maximize lifespan.

• Stainless-steel construction resists corrosion and high heat.
• Built for repeat outdoor use—from weekend brunches to large gatherings.
• Simple care practices extend usability and appearance.

Who is this for? The Stanbroil stainless-steel griddle insert is aimed at Weber Genesis II 400-series owners who want to broaden their grill repertoire beyond direct grilling. It's ideal for home cooks who prepare breakfast on the grill, entertainers who need to produce many items at once, and outdoor cooks who prefer easy cleaning and durable materials over cast-iron maintenance. If you regularly cook delicate or small items on your grill, or want a versatile flat-top for large gatherings, this insert gives you a reliable, spacious surface designed for your Genesis 4-burner grill.
