These cookers are designed with strength, durability, and function in mind. The top of this cooker is a large 12" x 12" square made from 1" angle iron and has rounded corners. The cooking surface is made with eight 1" x 1/4" flat bar spokes that are arranged so that they function well with either large or small pots. The legs are also made from 1" x 1/4" flat bar and are designed for strength and stability. The wind screen is heavy duty, 16 gauge sheet metal, even though it is not used for structural strength. These units may be purchased with either a high pressure or a low pressure cast iron burner.
