14" Half-Moon Ceramic Heat Deflectors for Large Big Green Egg Spiders

Flexible Indirect Cooking with the Spider in the Large Egg

These 14" half-moon deflectors are designed specifically for use with the CGS Spider in the Large Big Green Egg, giving you more control and flexibility than traditional one-piece deflectors.

Run one side or both depending on your cook. Whether you're setting up for big indirect BBQ, two-zone grilling, or a mix of both, the half-moon deflectors let you adapt your setup without being locked into a single configuration.

Why Half-Moon Deflectors

• Flexible setups — use one or both deflectors for partial or full indirect cooking
• Two-zone cooking — run direct heat on one side and indirect on the other
• Easier handling — smaller pieces are easier to place, adjust, and remove
• Better airflow — maintains proper airflow compared to solid one-piece plates
• Compatible — with 2.0 Handle and Original 3 & 5 Leg Spiders

Max Capacity Setup – Large Adjustable Rig

Use the 14" half-moons with the CGS Spider for big cooks on the Large Adjustable Rig.

Note: With the Spider 2.0, use the 13" x 17" Oval Grid inside the Rig on the lower level.

Running your heat deflection lower in the grill frees up space above for multiple cooking levels—making it easier to cook ribs, brisket, pork shoulders, or multiple items at once.

This setup gives you maximum cooking capacity while maintaining stable temperatures and proper airflow throughout the cook.

Double Indirect – PSWoo & Woo Rings

Use the 14" half-moons with the CGS Spider to create a lower heat barrier for double indirect cooks using the PSWoo or Woo Ring.

The upper deflector is your standard indirect setup on the Woo or PSWoo, creating a highly controlled, layered heat environment.

Two Zone – Direct & Indirect at Fire Ring Level

Use a single 14" half-moon to create a quick two-zone setup right at the fire ring level.

This is a simple way to grill smaller cooks or reverse sear steaks with direct heat on one side and indirect heat on the other.

Designed for the CGS Spider

These deflectors sit securely in the CGS Spider, placing your heat barrier low in the grill for efficient heat management and stable cooking temperatures.

This lower position helps protect your food from direct heat while still allowing proper airflow—key for long cooks like ribs, pork shoulder, and brisket.

Built for Kamado Cooking

• Durable ceramic construction — designed to handle high heat and long cooks
• Approx. 5/8" thick — balances heat retention and responsiveness
• Fits Large Big Green Egg when used with CGS Spider

Pizza Stone

The 14" half-moon deflectors can also be used as a pizza stone when placed together.

For best results, position both halves flat side up at the felt line or higher. Do not attempt pizza cooking at the lower fire ring level—heat is too intense and uneven.

Ideal placement is on the Large Adjustable Rig or, even better, on the Rig Extender to take full advantage of dome heat.

Tip: For thin crust pizza, try cooking with just the pizza stone and no lower deflector—think of it as a grilling-style cook. For thicker crusts like Chicago or Detroit style, use a blocking deflector below the stone for a more baking-style setup.

The 14" size is also a perfect match for the circular section in the Large Big Green Egg ConvEGGtor.

Setup Tip

Pair with a drip pan above the deflectors to catch grease and keep your ceramics cleaner during longer cooks.

Note: These deflectors are designed for use with the CGS Spider and are not intended to replace a one-piece ConvEGGtor.
