We were one the first to promote the benefits of using a half stone set-up in ceramic grills. The half stone is used to create two cooking zones when grilling. The first zone is direct (no stone) with the heat rising straight up from the fire and over the grid above. The second zone is indirect with the half stone knocking down the rising heat and producing a non radiating, lower temperature over the grid above.

The half stone set-up is handy when you need a holding or staging area during the cook. The most common example is grilling steaks from rare to well done. You can sear the steaks together and use the half stone configuration to hold the rare steaks until the well-done steaks are ready. Another example is having the half stone under veggies on a raised grid.

post it note for helpful tipThe Adjustable Rig provides three options to position a half stone right under a grid. Generally, it's either the 15" or 16" Half Ceramic Stone. With some grill's (Large BGE), the 15" Half Stone also fits the Spider for additional versatility - 4th option below. Check your grill's product Page for recommendations.

Option 1 uses our Half Stone Hanger and one Rig Crossbar to hold the half stone. The cooking grid is our 9"x18" Stainless Half Grid. The set-up goes to the backside of the Rig, so access to the grid below is unencumbered. If the Hanger and Half Grid are listed in your Grill's Adjustable Rig shopping section, this option is available for your grill.  The Hanger is a triangular wire form that hangs from the top of the Rig and holds the Half Stone. A Crossbar supports the back-end of the Hanger. The Half Stone is less than one inch under the grid. That is topside of the stone to topside of the grid. The set-up goes together quickly.

post it note for helpful tipThe Half Stone slides in and out easily. It's a convenient way to change between a direct and indirect set-ups. No need to handle anything but the Half Stone.

Option 2 uses the Rig Crossbars to hold the Half Stone, pictured below left. The grid is atop the Rig. The only restriction is the Half Stone must be set to one side.  

Option 3 uses another grid to hold the Half Stone, pictured below right. Having a grid under the Half Stone provides 360° stone placement. The lower grid can be elevated above the fire ring/box.

A 4th option is possible but does not use the Rig. It uses the Spider & Half Stone under a grid on the fire ring/box, pictured below. It's a perfect way to create zones when grilling on the fire ring/box. When you shop for Spiders. the recommended Half Stone will be listed in each Spider's product page.
