Which Char-Broil models and part numbers do these replacements fit?

How do the materials and dimensions affect cooking performance?

The grates are cast iron with a matte enamel finish that stores and distributes heat more effectively than thin or chipped porcelain coatings. The heavier rods and larger diameters increase longevity and searing capability while stainless heat plates protect burners and promote even flame spread.

• Grate sizes: narrow grate 18 x 6.5", two large grates 18 x 9.3", full configuration 18 x 25" total.
• Heat plates: stainless steel, 16 15/16 x 2 1/2" each for consistent coverage.
• Tube burners and carryover tubes: stainless tube burners 17 3/4 x 3/5" and extendable carryover tubes adjustable 5"–9.4".

What maintenance and care will extend the life of these parts?

Cast iron performs best with routine oiling and gentle cleaning; this prevents rust and preserves the matte finish. Use non-metallic tools to avoid scraping the enamel, and periodically check burner alignment and carryover tube length for optimal flame distribution.

• Season grates with a thin coat of oil before and after each use to protect the finish.
• Clean with a stiff brush or scraper designed for cast iron; avoid aggressive abrasives on the enamel.
• Inspect heat plates and burners for grease buildup and replace or reposition carryover tubes as needed.

Can I replace only individual pieces or do I need the full kit?

Yes — the kit lists individual parts and dimensions so you can match and replace single items like a narrow grate, a large grate, a heat plate or tube burner. Ordering only what’s needed saves cost and simplifies installation for experienced grill owners.

• Available in grouped packs: 3-pack grates (combination narrow + large) and 4-pack heat plates for common layouts.
• Measure your existing parts against the listed dimensions before ordering to ensure compatibility.
• Includes extendable carryover tubes if your model uses them—adjust length to fit.
