Product Description

Add Indirect, Two-Zone and Pizza Capability

CGS 14" half-moon ceramic heat deflectors are built for indirect cooking on kamados with 15" to 16" cooking grids.

Use one half-moon to create two-zone grilling, use a pair for full indirect BBQ smoking, or choose the full round stone if pizza is your main goal.

Common setups:

The 14" deflectors require a rack to hold them. Here are popular pairings.

  • Medium Big Green Egg: CGS Medium Woo
  • Large Big Green Egg: CGS Spider setups
  • Pit Boss 22 & Louisiana Grills 22: CGS Spider setups
  • Pizza: select grills with 14" to 18.5" diameter cooking grids

Choose Your Deflector

A heat deflector transforms your kamado into a smoker, two-zone grill, roaster, baking setup, or pizza oven. The half-moon shape gives you more control than a single round stone because you can choose how much of the fire to block.

One Half-Moon

Best for two-zone grilling. Block heat on one side while keeping the other side open for direct cooking.

Pair of Half-Moons

Best for full indirect BBQ, smoking, roasting and low-and-slow cooks.

Double Indirect & Big Cooks

For the Large EGG, use the Spider with 14" half-moons to create the lower heat barrier for double indirect setups or big meat cooks on the Adjustable Rig.

Full Round Stone

If you cook pizza often, go with a full round and dedicate it just for pizza. This helps keep your pizza stone free from grease and BBQ drippings.

When using a stone for pizza, create an air gap between the lower heat barrier and the pizza stone to help even out stone temperatures.

Three Benefits of Half-Moons

  • More options: use one or two depending on your cook.
  • Easier handling: half-moons are easier to place and remove than one full-round ceramic stone.
  • Lower replacement cost: if one half breaks, you only replace one side.

If your grill appears on the CGS website, check its product page for recommended rack systems, drip pans, spacers and setup details.

Remember a Drip Pan & Spacers

For BBQ cooks, we strongly recommend using a 14" stainless drip pan above the ceramic deflector. Ceramic can absorb grease and moisture over time. When trapped moisture heats up, it can steam inside the ceramic and add stress to the stone.

On BBQ cooks, CGS Ceramic Spacers can lift the drip pan off the deflector. This air gap helps reduce direct heat transfer from the ceramic to the pan, which can help limit burnt drippings during longer cooks.

Measure your setup first if vertical clearance looks tight.

FAQs

How does the 14" deflector compare to the Big Green Egg convEGGtor?

The CGS 14" deflector provides strong coverage for the Medium Big Green Egg and offers more flexibility than the one-piece convEGGtor. Use one half-moon for two-zone grilling or use a pair for full indirect cooking.

Will heat escape between two half-moons?

Yes, a small amount of heat can come through the gap between two half-moons, but the amount is minimal and does not meaningfully affect cooking performance.

Can I foil the deflectors?

You can, but creases in foil can create pinholes that may leak. Avoid wrapping the bottom side, as extreme heat could damage the foil.

Can they be used as both a deflector and pizza stone?

Yes. For frequent pizza cooks, we recommend using a dedicated pizza stone when possible. Using a drip pan during BBQ cooks helps keep the ceramic deflectors cleaner.

Can I high-heat clean burn the deflector?

We do not recommend aggressive high-heat clean burns. Using a drip pan greatly reduces the need for cleaning.

Are half-moons better than a full round?

If you cook pizza frequently, a full round is a great dedicated option. For most BBQ and grilling setups, we recommend half-moons for their flexibility.
