We are firm believers that this truly is "The Most Durable Grill Known To Man". When we get calls for Broilmaster repair parts or when long time Broilmaster grill owners decide to replace their grill, we have found that most of these existing grills are more than twenty five years old. One of our sales representatives owns a twenty eight year old D3 that is still going strong. How many other grill brands have a history of lasting this long? How many other grills consistently win "Best Buy" awards from leading publications? Most Broilmaster grills feature heavy cast aluminum housings, porcelain coated cast iron cooking grids, a 430 grade stainless steel bowtie-shaped main burner, a temperature gauge, a unique wind deflection shield and brass control valves. The cooking grids adjust to give you multiple cooking levels and are guaranteed for as long as you own your grill.
