Hongso Heat Plates are stainless-steel replacement flavorizer bars engineered to restore even heat distribution and protect burners on Broil King Baron and compatible grills.

Before ordering, confirm the shape and dimensions of your existing plates to ensure a match.

How do these plates affect grilling performance and maintenance?

By intercepting drippings and vaporizing them, flavorizer-style plates help reduce direct flame contact while adding grilled flavor. They also shield burners from debris, which lowers maintenance and helps the ignition and flame pattern remain consistent.

• Reduces flare-ups by vaporizing grease before it reaches the burner.
• Directs heat evenly across the grill for steadier searing zones.
• Makes burner cleaning easier by blocking accumulated grease and food particles.

How should I check fitment before I buy?

Measure your existing plates and compare the overall length and width to the Hongso dimensions. Also verify the plate shape and mounting orientation against your grill’s bracket layout to ensure a proper fit.

• Measure current plate: length 15.875" and width 6" for a match.
• Confirm the plate profile and any notch or bracket locations visually.
• Compare model numbers: compatible with many Broil King, Sterling, Broil-Mate, and Huntington Rebel variants listed in product details.
