Dacor has discontinued the 101164 black porcelain large grill grate. This item is an stainless steel replacement that will work for the 101164 Dacor grill grate, as well as the 72177 Dacor grill grate.
The measurements for this grill grate are 22" X 5-1/2". It is made from 304 grade stainless steel with rods measuring 7mm thick.
With the upgrade to stainless steel, you no longer have to worry about porcelain chips or rust in your food!
