Great Lakes Models has recently released two new products to the growing list.  Brand new n scale Manhole Covers, and Sewer Grates & Inlets. The sewer grates are exact scale replicas of the ones found at W. Duluth Ave and S. Massachusetts Ave in Milwaukee, Wisconsin.  Each piece is pre-scored for ease of assembly.
