The pattern that runs along the edges of our popular Chinook and Chinook 2000 products first started out as a trench grate. The elegant Double Wave pattern has been one of our most popular designs in the trench grate category, and it can be seen in cities across North America.
The Double Wave collection includes the Chinook Tree Grate, Chinook 2000 Tree Grate, and Double Wave Manhole Cover.
