The StormRax_™ slope series is designed for installation in your stormwater system with a square or rectangular concrete outfall structure that has a knee wall and requires a trash rack for debris screening. The fiberglass reinforced structural High Density Polyethylene (HDPE) construction is engineered to endure the harshest of environments and ensures your stormwater system is ready when Mother Nature is at it’s worst. See below for the slope series with downloadable drawing and available options.
