GLOWYE Griddle Insert for Weber Genesis II 300 Series — Full-Size 25.6×18.7in Carbon-Steel Flat Top with Dual Handles

The GLOWYE 6788 full-size griddle insert converts your Weber Genesis II 300 Series gas grill into a versatile flat-top cooking surface for pancakes, burgers, eggs and stir-fries.

This heavy-duty carbon-steel griddle plate fits full-width on compatible Weber Genesis II 300 Series models (including E-310, E-315, E-325, E-330, E-335, S-310, S-335 and LX variants) and replaces factory grates with a flat, non-stick surface. Measuring 25.6" wide by 18.67" deep and 1.19" high, the plate is built to resist warping, control grease, and give you consistent heat across the whole cooking area. It arrives with dual handles for safe handling and an integrated grease-tray system to keep flare-ups and mess to a minimum.

How does this griddle fit my Weber Genesis II 300 Series grill?

The GLOWYE 6788 is designed as a full-size insert that lies across the grill frame where the factory grates sit. It is made to match the footprint of 2016 and newer Genesis II 300 models so you won’t sacrifice stability or airflow. Installation is a simple lift-and-set process with the dual handles helping you position the plate precisely.

• Fits Genesis II 300 Series models (E-310, E-315, E-325, E-330, E-335, S-310, S-335, LX and related variants)
• Dimensions: 25.6" W x 18.67" D x 1.19" H for full coverage
• Dual handles align with existing grill supports for secure placement
• Works with GS4 Genesis II setups that accept full-width grates

What can I cook on this flat-top griddle and how does it perform?

The flat, continuous surface is ideal for foods that need an even sear or benefit from a barrier between direct flame and food. It gives reliable surface contact for pancakes, eggs, bacon, burgers, steaks, quesadillas, crepes, and quick stir-fries. The carbon-steel construction heats evenly and retains heat so you get consistent browning across the plate.

• Great for breakfast items like eggs and pancakes without falling through grates
• Perfect for searing steaks and burgers with consistent contact
• Useful for small-flame stir-fries and flatbread or quesadilla cooking
• High sidewalls reduce grease splatter and keep food contained

How do I care for and maintain the carbon-steel griddle?

The griddle arrives with a non-stick coating that benefits from seasoning before first use and occasional re-seasoning to maintain performance. Clean by hand—avoid abrasive scrubbers and never put it in a dishwasher—to protect the coating and prevent rust. The included full-width grease tray makes cleaning faster by collecting drips away from the cook surface.

• Season before first use: wash, oil thinly, heat until smoking, cool, repeat 2–3 times
• Hand wash only; use soft cloths or non-abrasive pads to protect coating
• Empty grease tray after each session to prevent buildup and flare-ups
• Store dry and lightly oiled to prevent surface oxidation

Is this griddle durable and safe to use on my gas grill?

Constructed from heavy-gauge carbon steel, the plate resists warping under high heat while its rust-resistant finish helps extend service life. The raised sidewalls and full-length grease catch reduce flare risk and make the griddle safer for frequent use. Handles remain cool to touch longer than the plate, improving safe handling when repositioning.

• Thick carbon-steel resists warping and stands up to high heat
• Rust-resistant finish and protective coating for longer life
• Integrated grease-tray and high sidewalls minimize splatter and flare-ups
• Dual handles for secure lifting and alignment

Who is this for: The GLOWYE 6788 full-size griddle insert is aimed at home grillers who own a compatible Weber Genesis II 300 Series unit and want to expand cooking options—especially those who cook breakfasts, flatbreads, or many small items at once. It’s also suited for anyone who wants a durable, easy-to-clean flat-top surface without replacing their entire grill.
