The first time you pick up these 18.5" half-moon ceramic heat deflectors, your reaction will likely be: “Damn, these things are thick and heavy!” Built to handle serious heat, we partnered with a globally respected ceramic supplier to maximize durability and thermal resistance. After countless cooks, we can confidently say—they perform just as good as they look.
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.
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.
Don't forget to add our 18" Stainless Drip Pan – perfect for protecting the deflector and keeping the grill clean on long, messy, barbeque cooks.
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.
The 18" Deflectors must be used with the Divide & Conquer Accessory Rack (BJ-XR). Only Kamado Joe Deflectors (~19") will fit the lowest ring position. For barbeque cooks, we recommend using the Deflector on the Accessory Rack whenever possible—it provides better spacing and airflow than placing a deflector on the D&C's lowest ring position .
One 18" Half-Moon Deflector is the perfect size for under the 20" Half Grid on the Pit Boss 24 Adjustable Rig.
Approximate stone specifications are 18-1/2" diameter, 3/4" thickness, and high-heat refractory ceramics. A full round or pair of half-moons weigh approximately 13.6 lbs.
Best to set the stone in the grill as it comes to temperature to prevent thermal shock. Ceramic stones absorb moisture like sponges, so protect the topside of the stone with foil or a drip pan.
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 darken over time from absorbing smoke during cooks.
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.
