PRODUCT BRIEF

Introduced in 1990 as a compliment to our Double Wave trench grate line, the Chinook model features our signature interlocking wave pattern wrapped around a simple band of concentric squares. Since its introduction to the market, Chinook has found a home in the sidewalks of cities from Auburn, WA to Lafayette, IN.

We take pride in this stalwart design’s ubiquity, and also in the “inspiration” it has offered some competitors.
