Will these grates fit my Weber Smokey Mountain 18"?

These grates are designed to match the common Weber 18" Smokey Mountain parts. They correspond to the OEM part numbers frequently used for upper, lower and charcoal grates, but you should verify measurements of your original pieces before purchasing.

• Upper cooking grate: approximately 17.5 inches across
• Lower cooking grate: approximately 17 inches across
• Charcoal support grate: approximately 15.25 inches across
• Compatible with many Weber part numbers such as 7432, 85042, 63013 — confirm your model first

How durable and easy to maintain are these grates?

Constructed from plated steel, the grates resist rust and clean up more quickly than raw steel. The plated finish helps prevent food from sticking and simplifies routine washing after a cook.

• Plated-steel surface for corrosion resistance
• Smooth finish reduces food adhesion and rescues scrubbing time
• Raised side handles on cooking grates make lifting safe and simple
• Charcoal grate supports fuel while prolonging smoker life by reducing direct ash contact

What does the package include and how are the grates used?

The kit contains one upper cooking grate, one lower cooking grate and one charcoal grate. The cooking grates rest on existing ledges in the smoker bowl and remove easily via the integrated side handles; the charcoal grate sits near the bottom to keep fuel elevated for better airflow.

• 1 x upper cooking grate (fits upper rack position)
• 1 x lower cooking grate (fits middle or lower cooking position)
• 1 x charcoal grate (holds briquettes or lump charcoal, aids airflow)
• Designed as direct replacements—swap them in without tools

How do these grates improve cooking performance?

Replacing worn or warped grates restores even heat dispersion and consistent airflow through the charcoal bed, which helps maintain steady smoking temperatures. The charcoal grate also prevents ash saturation beneath fuel, which helps keep burns efficient and easier to manage.

• Re-establishes stable cooking surfaces for even heat contact
• Charcoal grate improves air circulation and fuel combustion
• Raised handles let you reposition cooking grates without touching hot metal
• Plated finish makes post-cook cleaning faster and less abrasive

Who is this set for? This Uniflasy three-piece grate set is ideal for Weber Smokey Mountain 18" owners who need OEM-style replacements without buying a whole smoker. It suits backyard smokers who want durable plated-steel parts, weekend cooks who prefer easy cleanups, and anyone restoring vintage or heavily used Smokey Mountain units. Confirm the grate measurements and your smoker's part numbers before ordering to ensure a perfect match.
