These two-piece grates replace factory bars to restore cooking performance and durability for compatible Genesis II 300 and LX 300 models. Crafted from food-grade SUS304 stainless steel with 7mm solid rods, they resist corrosion and warping while providing consistent heat transfer and long-term reliability. Before ordering, confirm your grill model and the overall grate dimensions to ensure a perfect fit.

Which Weber and KitchenAid models do these grates fit?

• Also fits KitchenAid: models 720-0954 and 720-0954A

How are these grates built and why does that matter?

The grates use heavy-gauge SUS304 (food-grade 18/8) stainless steel with 7mm solid rods for each bar; this construction improves longevity, heat stability, and resistance to rust compared with thinner rods or plated alternatives.

• SUS304 stainless: non-magnetic, corrosion resistant, safe for food contact
• 7mm solid rods: stronger and less likely to warp under high heat than 5mm bars
• Thicker cross-section: better heat retention and even sear lines on food
• Two-piece set: matches factory layout for easy installation

What are the exact dimensions and what should I measure on my grill?

Each individual grate is 18.75" x 13.25"; together they form a full cooking surface of 18.75" x 26.5" when placed side-by-side. Measure your existing grate length, width, and mounting tabs to confirm compatibility before purchase.

• Single grate size: 18.75" (front-to-back) x 13.25" (left-to-right)
• Total assembled size: 18.75" x 26.5"
• Check mounting tab positions and model year (2017+) for correct fit
• Compare against OEM part numbers listed above if unsure

How do these grates affect cooking performance and maintenance?

The larger-diameter rods provide better thermal mass for steadier heat and clearer sear marks, while stainless construction simplifies cleaning and reduces scale buildup versus cast-iron grates that require seasoning.

• Improved heat distribution: firmer sear and reduced hot/cold spots
• Lower maintenance: stainless resists rust and is dishwasher-safe for small tools
• Durability: thicker rods withstand frequent grilling and high temperatures
• Easy swap: installs like OEM grates with no tools in most cases

Who is this for? These QuliMetal 18.75" stainless steel grates are ideal for Genesis II 300 and LX 300 series owners who want a long-lasting, low-maintenance replacement that preserves OEM fit and improves searing performance. Choose them if you need a direct-fit substitute for worn, rusted, or damaged factory grates and if you prefer stainless over cast-iron for easier care. If you have a different Weber model year or non-compatible dimensions, verify measurements or consult product compatibility before purchasing.
