Designed in collaboration with notable landscape architecture firm Peter Walker and Partners, the Jamison Tree Grate is streamlined and modern. Named after the award-winning Jamison Square in Portland, Oregon—a project for which it was created— this grate uses simple geometries to produce an adaptable, durable, and popular design seen in city sidewalks across the country.

The Jamison collection includes the Jamison Trench Grate, and Jamison Drain Cover.
