Our exclusive designs use precision cut hardware, which allows for an easier and more secure installation, improved performance and a more stable flame. The media support plate is designed to allow maximum airflow and preventing overheating, sagging and warping. The four-bolt system allows for an easy installation to the mounting surface, which provides a more secure and stable product. The mounting bracket includes corrosion resistant stainless steel studs and is powder coated in a non-reflective bronze color to blend with the oil rubbed hammered copper. Cast stone bowls do not have a mounting bracket, as the mounting feet are cast into the cast stone bowls for an extremely stable mount. The feet allow airflow to the burner electronics and provide a cleaner and richer flame.
