Direct Store 18" Cast Iron Plate Setter for 18" Kamado Grills — Large Heat Deflector & Pizza Stone with 3 Legs

The Direct Store DC143 is a heavy-duty 18" cast iron plate setter designed to convert large Big Green Egg and other 18" kamado grills into reliable indirect smokers, pizza stones, griddles, and heat deflectors.

If you want a single accessory that expands your 18" kamado’s versatility — from low-and-slow smoking to high-heat pizza searing — this cast iron plate setter delivers a broad, stable cooking surface and rugged longevity. Machined as a three-legged 18" diameter disk with a 14" grate area, it’s made from dense cast iron to hold heat consistently and support heavier cookware or multiple items at once.

How does this plate setter improve indirect cooking on my 18" kamado?

Placed between the fire and the cook surface, the DC143 blocks direct flame while retaining and spreading heat evenly across the cooking area. That creates stable ambient temperatures ideal for smoking, roasting, and baking without flare-ups or hot spots.

• 18" outer diameter with 14" usable cooking grate for expanded capacity
• Three-legged design raises the cooking surface and improves air circulation
• High-density cast iron smooths temperature swings and stores heat
• Can be flipped to act as a griddle or pizza stone for direct-contact cooking

Can I use it as a pizza stone, griddle, or regular cooking surface?

Yes. The cast iron plate setter functions as a multi-purpose surface: use it flat-side-up as a griddle for searing, flip it to the smooth side for pizza baking, or keep it as a heat deflector for indirect methods. Its material and thickness help develop good crusts and even browning.

• Flip-over capability lets you switch between indirect and direct-contact cooking
• Cast iron provides crisp searing and strong heat retention for pizzas
• Large surface area allows multiple items or larger pizzas simultaneously
• Stable three-leg support prevents wobble with heavier pans or grills

What are the dimensions, material, and care recommendations?

The DC143 measures 18" overall in diameter with a 14" grate diameter and stands about 2.5" tall. It’s cast from dense iron for long-term durability but needs simple maintenance to preserve seasoning and prevent rust.

• Overall diameter: 18"; grate diameter: 14"; height: 2.5"
• Made from high-density cast iron for steady heat distribution
• Hand-clean with hot water and mild detergent; use a soft brush or salt for stubborn residue
• Avoid dishwashers, harsh soaps, or steel wool; dry fully and store sealed to protect seasoning

Will this fit my Big Green Egg or other 18" kamado models?

The DC143 is sized for grills with an 18" cooking chamber and will suit many large Big Green Egg models and comparable 18" kamados. Because cast iron tolerances and grill interiors vary, confirm internal diameter before purchase to ensure a comfortable fit.

• Designed for large 18" kamado grills and Big Green Egg equivalents
• Slightly larger than some factory heat transfer plates for extra cooking room
• If unsure, measure your grill’s internal diameter and compare to the 18" overall size
• Contact support if shipping damage occurs — cast iron can crack in transit

Who is this for: The Direct Store DC143 is ideal for backyard cooks who want to expand a single 18" kamado into a multi-function appliance — hobbyist smokers, outdoor pizza lovers, and anyone who needs a durable, heat-stable surface for larger or multiple dishes. It suits users comfortable with basic cast iron care and who want a heavier-duty alternative to ceramic stones and thin heat deflectors.
