This is our 36 Triple Ring Stainless Steel Burner Ring. Our Stainless Steel Burner Rings are the Highest Quality and Heaviest in the industry! It has a 3/4 Pipe Thread Center Hub for higher gas capacity with a Flush Hex Key Plug and the Hex Allen Key included so that you can plug either side to have your burner holes either face up or face down. The center hub is also offset slightly so that if you install this burner with the holes facing up if any water seeps in, it won't get into your gas line. All holes are drilled and not punched like other manufacturers burners. Punched holes cause whistle and mean that the burner is made out of thin material. Unlike other manufacturers burners, our burner has the rings evenly placed. Most manufacturers just add another ring to the outside of their smaller rings and the rings are not even. You won't be disappointed in the quality and performance of this burner. Features Type Fire Pit Burner. Burner Type Triple Ring. Material Stainless Steel. Fire Pit Burner with 3/4 Hub.
