Olympia Rectangular Indent Rock Grate

Olympia Rectangular Rock Grate with Indents. 11 1/8" x 16 1/16". The depth (front to back) of a replacement grate should be within three sixteenths of an inch (0.1875) of the original parts depth. The width of a grate is much less critical. A replacement can be a few inches narrower than the original and still be useful.
