This is a grill grate I found at my parents' house. I've washed it, but there are some burnt spots from use. Since I only use Rinnai, I assume the manufacturer is Rinnai. I don't know the model number. It's 27.5 cm tall and 25.5 cm wide. There are protrusions on both the top and bottom, presumably where the grate sits in the second row. The width of the protrusions is about 2 cm, and the height is about 1.5 cm. I cannot offer a discount on this price if you choose anonymous shipping. A discount is possible if you choose regular mail (non-anonymous).
