Stanbroil Flavorizer Bars for Weber Summit 400 Series Grills — 9 PCS Stainless Steel, Thicker Durable Heat Shields

These Stanbroil stainless steel flavorizer bars replace worn heat shields in Weber Summit 400 series grills to protect burners, vaporize drippings and help deliver even cooking with added smoky flavor.

When your grill’s original heat shields are rusting or warped, replacing them with durable, corrosion-resistant bars restores even heat distribution and shields burners from dripping grease. This nine-piece Stanbroil set is sized to match Weber Summit 400, Summit E-420 and S-420 models, offering thicker stainless steel construction, chamfered edges for safe handling, and a smooth finish that makes cleaning simple.

How do these flavorizer bars protect my grill’s burners?

Stanbroil bars sit above the burners to catch drippings and block direct flames, reducing flare-ups and extending burner life. By redirecting heat, they help the burners heat more evenly and prevent grease from falling directly onto the flame.

• Full-size pieces: each bar measures 18" x 1.7" x 1.2" to match Summit 400 layouts.
• Thicker stainless steel resists warping under high heat.
• Chamfered edges reduce the risk of cuts while installing or cleaning.
• Protects burners by catching oils and food drippings before they reach the flame.

Will these fit my Weber Summit 400 or E-420 grill?

These flavorizer bars are made to be compatible with Weber Summit 400 series grills and related models listed by Stanbroil. Always verify your original part dimensions and model numbers to ensure correct fit before purchasing.

• Compatible with Weber Summit 400 series, Summit E-420 and S-420 (fits models 7121001, 7120001, 7221001, 7220001).
• Nine bars per pack to replace an entire cooking area shield set.
• Measure your existing bars and compare to the stated 18" x 1.7" x 1.2" size.
• Aftermarket part — not an OEM Weber item; sizing verification recommended.

How do these bars affect flavor and cleanup?

When drippings strike the hot stainless steel they vaporize and re-condense as smoke, subtly boosting grilled taste; at the same time the smooth stainless surface prevents heavy buildup. Routine wiping or a quick wash with soapy water usually removes residue, making maintenance straightforward.

• Vaporizes drippings to add smoky notes without direct flame charring.
• Smooth finish resists sticking and simplifies cleaning by hand.
• Stainless material reduces corrosion compared with thinner metals.
• Dry thoroughly after washing to prevent spotting and prolong life.

Who is this for? Grill owners with Weber Summit 400 series or compatible Summit E-420/S-420 models who need a tougher, longer-lasting replacement for degraded heat shields. It’s ideal for frequent grillers who want improved burner protection, easier cleaning, and a subtle flavor boost without replacing the entire grill. If you’re comparing parts, confirm your model number and measure your original bars first — this aftermarket Stanbroil set provides a cost-effective way to restore performance and protect internal components while keeping your food evenly heated and tasting great.

Care tips: Clean bars after each use when cool, remove excess grease before storage, wait to apply sugary sauces until final minutes of cooking, and coat and wrap parts for long-term storage to reduce corrosion.
