GrateGator

Above Grate Filter

This above-the-grate stormwater filter removes sediment and debris from stormwater as it enters the catch basin. The device is a durable, high-flow filter. Clean, maintain, and reuse it for the duration of your construction project. With built-in overflow protection, it efficiently filters contaminants while allowing bypass during extreme wet weather events.
