Question: Since this product is to be used to cook with, what is it made of? Is it zinc coated? Stainless? Chrome? How many screens come with purchase?
Document: Used this with the Big Chief Smoker. I thought this was a good idea of the makers of this product and gave it a try. I was making jerky for the troops a work as gift. Bottom line is that the the three of the five racks had varying degrees of melt stages around the edges. The worst was at the bottom rack. How's black sound? I did used only 3 pans of hickory chips as called for, so I know that I didn't over tax these screens with heat.
Who knows. Seems to me that in a small way it's waste of smoke and effort that shouldn't be required.. I think that if Big Chief had made the racks of stainless steel with 1/4 inch squares I would of paid the extra cash and saved time and money. Good Luck.Jeff Merritt
