Onlyfire 24-Inch Cooking Grate Deflector Alternatives: 6 Similar Picks Compared
As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
The onlyfire BBQ cooking grate system alternatives list helps you find compatible parts when the original does not fit your needs. The Onlyfire 24-Inch Cooking Grate and Deflector System expands your cooking surface on a 24-inch Kamado Joe Big Joe. It includes stainless steel half-moon grates and deflectors that sit securely on the original grill tabs. This setup separates food from coals and allows for multi-level indirect cooking. You get a stable base rack that prevents spinning while you cook.
You might look for other options if you own a different grill size or prefer cast iron over stainless steel. The alternatives in this guide were chosen because their specs overlap with the original product. Some replacements fit 18-inch or 22-inch models, while others offer reversible griddle surfaces. This list covers 6 similar picks that match your grill style. You can compare materials, dimensions, and compatible appliance models to find the right fit for your outdoor cooking setup.
How these picks differ from Onlyfire
Charbrofire Genesis II 300 Stainless Steel Grates Kit
This Charbrofire kit targets Weber Genesis II 300 owners, not Kamado users. It provides a full replacement set including grates, bars, and deflectors for models from 2017 onward. The dimensions are 18.74 by 26.5 inches. You get stainless steel parts that replace multiple components in one purchase. Unlike the Onlyfire system, which adds a separate cooking layer to a Kamado, this kit replaces the existing structure entirely. It is the right choice if you own a Weber Genesis II and need a complete hardware refresh rather than an expansion kit for a ceramic grill.
Kamado Joe Classic Reversible Cast Iron Griddle
The Kamado Joe Classic Reversible Cast Iron Griddle offers a different cooking approach. It is made of cast iron, whereas the Onlyfire system uses stainless steel. This griddle weighs 7 pounds and measures 18.3 by 8.98 inches. It provides excellent heat retention for searing, which stainless steel grates do not match. You give up the expanded indirect cooking surface area of the Onlyfire system. Instead, you gain a dedicated flat-top zone. This pick suits Kamado owners who prioritize versatile cooking zones and modular systems over maximum grilling surface area.
BBQration 18 3/16-Inch Cast Iron Grate
This BBQration grate is a direct replacement for Big Green Egg Large grills. It is made of cast iron and weighs only 1 pound. The dimensions are 19 by 10 inches. It fits the 18 3/16-inch size specification. Unlike the Onlyfire system, which adds a deflector and extra rack, this is a single grate. You sacrifice the ability to separate food from coals using an added layer. This option is for Big Green Egg owners who want a durable cast iron grate that retains heat well and requires regular oil maintenance.
Charbrofire 9.75-Inch Cast Iron Fire Grate
The Charbrofire fire grate sits at the bottom of the grill, not on top. It is a 9.75-inch cast iron base replacement for Kamado Joe Classic models. It weighs very little and measures 10 by 10 inches. This part holds the charcoal, not your food. You cannot use it to cook directly like the Onlyfire grate. It is designed for easy ash cleanup and durable construction. Pick this if you need to replace the burnt-out base of your Kamado Joe Classic rather than expanding your upper cooking surface.
Cmanzhi 18-Inch Cast Iron Grate and Griddle Set
This Cmanzhi set is designed for 18-inch ceramic grills. It includes a cast iron grate and griddle that weigh 15 pounds total. The grate is 18 inches long. It is much heavier than the 7.41-pound Onlyfire stainless steel system. You gain heavy-duty heat retention and versatile cooking options with a griddle surface. You lose the lightweight, rust-resistant stainless steel construction. This set is for 18-inch ceramic grill owners who want to expand their cooking options and do not mind the maintenance required for cast iron cookware.
Terefour 18-Inch Cast Iron Grate and Griddle Set
The Terefour set provides a reversible cast iron grate for 19-inch dimensions. It measures 19 by 9 inches and weighs significantly less than the Cmanzhi option. It offers both grilling and griddle surfaces. Unlike the Onlyfire system, which uses stainless steel for indirect cooking expansion, this is solid cast iron. You get searing marks and griddle flexibility. You give up the convenience of a separate deflector plate. This pick is for Kamado owners who want versatility in their cooking surface and prioritize searing capabilities over maximum indirect cooking space.
