DELSbbq Full-Size Flat-Top Griddle Insert for Weber Spirit 300/400 Series (2025) — Nonstick, Heavy-Duty

DELSbbq's full-size flat-top griddle converts compatible Weber Spirit gas grills into a roomy, nonstick griddle surface for pancakes, eggs, smash burgers, and other flat-top favorites.

If you want to expand what your Weber grill can do without buying a separate appliance, this heavy-duty griddle insert is designed to fit Spirit 300 and 400 series models (including 2025 Spirit 4-burner models) and many Genesis and Smokefire variants. The 22.6" x 17.4" cooking surface replaces standard grates in seconds and provides a flat, fast-heating platform that holds heat evenly while protecting burners. It ships with a handle and heat-resistant gloves for safer handling and includes care guidance so the surface stays smooth and long-lasting.

How does the griddle fit my Weber Spirit or compatible grill?

The insert is shaped to match full-size Weber Spirit grates and is listed as a replacement for part 6787 and many similar grate models. It fits Spirit I & II 300 series (E/S 310 and 320 variants), Spirit 400 Series 2025 models (E425, S425, E435, EP425), and a broad range of older Genesis and Smokefire models where a full-size flat insert is used.

• Dimensions: 22.6 inches long × 17.4 inches wide for full grate coverage.
• Direct fit for Spirit 300/400 series models noted, plus many Genesis and Smokefire grills.
• Designed as a drop-in replacement to use with existing flavorizer bars/heat plates.

What can I cook on the DELSbbq griddle and how does it perform?

The flat top converts your grill into a versatile cooking surface for delicate and small items that fall through grates. It heats quickly and distributes heat across the plate so you can sear burgers, fry eggs, or make pancakes with consistent results and minimal flare-ups.

• Great for breakfast items: eggs, pancakes, hash browns, and bacon.
• Perfect for quick-cook items: smash burgers, quesadillas, stir-fries, and vegetables.
• Nonstick surface for easy release and faster cleanup when oiled properly.

How do I install and care for the griddle to ensure long life?

Installation is simple: remove the grill grates and lower the griddle into place over the flavorizer bars—no tools required. For maintenance, clean gently after each use, lightly oil the surface before cooking, and dry and oil again before storage to protect the finish and prevent rust.

• Includes handle and gloves for safe placement and removal.
• Wash with warm, soapy water before first use and after cool-down; avoid metal utensils.
• Dry thoroughly and apply a thin layer of oil before storing to extend lifespan.

Will using the griddle change how my grill heats or affects burners?

The griddle is engineered to work with your grill's existing flavorizer bars and burners so heat spreads evenly and the plate reaches cooking temperature faster. Leaving the heat plates in place helps shield burners from drippings and maintains efficient heat distribution while you cook on the flat surface.

• Designed to be used with flavorizer bars left in place for even heat transfer.
• Spreads heat across the full plate to minimize hot spots and improve searing.
• Protects burners from excessive drippings, reducing maintenance needs.

Who is this griddle for? Home grillers who want to broaden their outdoor cooking repertoire without buying a second appliance will benefit most: families who cook breakfast outdoors, barbecue enthusiasts who want better smash burgers and stir-fries, and anyone who owns compatible Weber Spirit/Genesis/Smokefire models and needs an easy, durable replacement for worn grates. If you prefer simple installation, even heat, and a large nonstick surface for crowd cooking, DELSbbq’s full-size griddle is a practical upgrade.
