KAMaster 17" 304 Stainless Steel Bottom Fire Grate for XL Big Green Egg — Improved Airflow & Faster Ignition

The KAMaster 17" 304 stainless steel bottom fire grate is a heavy-duty replacement charcoal grate engineered to improve airflow, speed ignition, and simplify ash cleanup in XLarge kamado and 22" kettle-style grills.

If your ceramic or cast-iron grate is slowing down startup, trapping ash, or making temperature control sluggish, this 17-inch stainless steel fire grate is built to help. Made of 304 food‑grade stainless steel with approximately 5 mm bars, it fits many XLarge Big Green Egg fireboxes and common 18½–22" cookers, offering a durable, rust-resistant alternative to original grates.

How does this grate improve lighting and temperature control?

The open-bar design substantially increases bottom-airflow under the coal bed, letting charcoal ignite faster and maintain more consistent burn patterns. Better airflow means quicker response when you adjust the dome or bottom vents, so dialing in low-and-slow or high-heat searing becomes easier.

• Thicker 5 mm bars resist warping under high heat for even air channels.
• Open spacing prevents ash from smothering coals, keeping vents effective.
• Stainless surface lowers heat absorption compared with cast iron, promoting quicker temperature shifts.

Will this fit my XL Big Green Egg or Weber-style 22" grill?

This 17" round grate is sized for the XLarge Big Green Egg firebox and is also compatible with many 18½"–22" kettles, smokers, and kamado-style cookers. Always check your firebox diameter and clearance before ordering to confirm fit.

• Designed to fit XL Big Green Egg and similar XLarge kamado fireboxes.
• Works with 18½" Smokey Mountain Cooker and several 22" kettle/charcoal grills when clearance allows.
• Measure inside diameter and grate-to-dome distance to ensure proper installation.

How easy is it to clean and maintain compared with cast iron or porcelain grates?

304 stainless steel resists clogging and doesn’t require frequent re-seasoning like cast iron. The open-bar layout sheds ash and leftover charcoal more readily, so routine maintenance is faster and the grate stays functional longer under repeated high-heat use.

• Non-porous stainless surface reduces ash adhesion and carbon buildup.
• Simple brush-and-brush-off cleaning; occasional soak for stubborn deposits.
• Longer service life without flaking or chipping common to porcelain-coated grates.

Who is this for? The KAMaster 17" bottom fire grate is aimed at backyard cooks and pitmasters who want a reliable, long-lasting replacement for worn or restrictive fire grates. It suits owners of XLarge Big Green Egg kamados, 18½" smokers, and many 22" kettle-style grills who need faster startup, cleaner ash management, and crisper temperature control without replacing the entire firebox.

Features at a glance: heavy-duty 304 stainless steel construction, ~5 mm bar thickness, improved airflow for faster lighting and easier temperature management, ash-resistant design for quick cleaning, and compatibility with many XLarge and 18½"–22" grills. Check your grill’s inner dimensions before purchase to ensure a correct fit.
