Overview
Charcoal fuel type and a light 2.38 pound build point to the onlyfire F-GCG8520-RS1 being a grate style replacement part for a charcoal grill's firebox, sized 17.52 x 9.21 inches.
Charcoal in the specs points away from a gas burner and toward something that sits in the fire box, such as a charcoal or ash grate. At 2.38 pounds for its size, the piece is likely open wire or mesh construction rather than solid cast metal.

Performance notes
At 2.38 pounds spread across a 17.52 by 9.21 inch area, the part is light for its size, consistent with wire or perforated construction that lets ash fall through while holding coals or fuel above it. That kind of open design is standard for charcoal grates rather than solid plates.
