Pizza Stone: XL size pizza stone for round grills with a 22 inch or larger diameter cooking grid. This includes the XL EGG, Big Joe and Weber Charcoal Summit.

Pair vs. Full: A pair will typically be your best choice as they are easier to move in/out of a rack system and provide more capability. Pairs can be used for pizza too. Check specific Flexible Cooking Systems (racks) to verify best use.

Important Deflector Protection: Check our 18" Stainless Drip Pan - perfect for protecting the deflector and keeping the grill clean on long, messy, barbeque cooks.

XL Big Green EGG: The 18" Pair and Full Deflectors match the diameter of EGG's XL ConvEGGtor. A pair of 18 Half-Moons are cheaper than EGG's ConvEGGtor and offer more functionality when used with an Expander or Adjustable Rig.

Big Joe: The 18" Deflectors must be used with the Divide & Conquer Accessory Rack, BJ-XR. Only Kamado Joe Deflectors (~19") will fit the Divide & Conquer lowest ring position. Note, for barbeque cooks, we recommend using the Deflector on the Accessory Rack when possible - it provides better spacing and airflow vs. a Deflector at the lowest ring position. 

Size: Approximate stone specifications are 18-1/8" diameter, 3/4" thickness and high heat, refractory ceramics. Stones can vary from 18" to 18-1/4" diameter.

Use: Best to set the stone in the grill as the grill comes to temperature to prevent thermal shock. Ceramic Stones absorb moisture like sponges, so protect the topside of the Stone with foil or drip pan.

Care: Do not oil or use dish detergents on the stone. Do not clean with high heat or in the dishwasher. To clean scrape debris off and heat at moderate temperatures. They will turn dark from absorbing smoke during cooks.

Ceramic Spacers: CGS Spacers provide two useful set-ups. (1) On pizza cooks, spacers can lift the pizza stone above the ConvEGGtor or heat deflector. (2) On barbeque cooks, spacers can lift the drip pan above the heat deflector.

The 18" Half Moon Ceramic Stones were exactly what we wanted. Thanks.

Heat Deflector / Drip Pan

I now have 3 cooks with the 18in Heat Deflector / Drip Pan combination and this is fantastic. This takes indirect cooking to another level. I wrap the drip pan in foil for easy cleanup. The drip pan doesn't get so hot that the drippings burn excessively which changes the flavor of the food. I am now looking to cook more large cuts of meat with this combination especially when you want to save the drippings. This combination is my favorite way to cook the Kamado K7.

Big Joe Kamado Joe® - Heat Deflector

Love these Deflector's especially the price and quality of these Deflectors are great quality. You will not be disappointed. Shipping is extremely fast.

Cracked after 3 cooks

Maybe the manufacturer changed since all the good reviews back in 2016 but this one didnt hold up. Only use for pizza on the egg and cracked after 3 cooks. My BGE stone i have had for 10+ years still going strong.

Exactly as you would expect from Ceramic Grill

When combined with the Woo it will make you retire your BGE plate setter. This is extremely well made and easy to handle.
