This is a genuine OEM replacement part for American Range commercial kitchen equipment. It's a top grate, made from heavy-duty cast iron, measuring 5 inches wide by 17 and 3/4 inches long. If you've got a restaurant range, hotel kitchen stove, or other professional-grade American Range appliance and the old grate is cracked or worn out, this is the exact part you need to get it back in service. Using the real OEM part ensures it fits perfectly, handles the heat without warping, and supports your heavy pots and pans safely. It's a straightforward swap - just lift off the old one and drop this in its place. Made in the USA. Always a good idea to double-check your model number to confirm fitment, but if you know you need part number A17017, this is it.
