  • Filter insert for curb inlet drain
    Patent number: 8475655

The support bar is configured to rest outside of the basin against curb face sides bounding the opening in the street level curb face. A support frame is coupled to a second side of the upper end of the filter bag and is configured to engage with the support bar to suspend the support frame substantially at grade within an interior of the basis and define a rigid opening into the filter bag. The remainder of the filter bag hangs below grade within the curb side drain basin.
