I assumed the mps would sit on the grill grate for whatever grill you have, is this to raise the stone into the "dome" and closer to the heat?
That's right plus few more potential usesThe leg base:
It can be screwed directly to the MPS. It will help keep MPS ˝” off the grill grates to keep it away from the grease on the grill grates and to keep it clean. Also, it will make it easier to place or slide on the grill grates.Leg extensions:
It will fit between MPS and the leg base mentioned above. This will allow raising MPS 3” higher. It will bring MPS closer to your grill cover which gets hotter, which will reduce your baking time. And potentially use the space below MPS to cook some foods while making pizza.Two leg extensions:
You can add more extensions to increase MPS’s legs length by 3” increments. For example, use two legs extension to raise MPS by 6”, to place firewood under MPS and use MPS as a standalone outdoor cooking device.
This is useful for cooking while camping. You can use the MPS heat diffuser with legs to cook food over a wood fire. Instead of the stone you can place any pan and cook your meal as you would cook on a stove top. This is a much lighter and less expensive option than using cast iron pots and pans. The heat diffuser will diffuse the heat from the wood placed right under MPS which you can adjust the heat by adjusting the three screws and gap between your pan and the MPS heat diffuser.
