French Drain Skimmers (or FDOT Type II Skimmers) is a hooded cover, mounted over an outlet in a catch basin, that prevents oil and floating debris from exiting the basin. French Drain Skimmers should be used in French drain catch basins and in other locations where there is a need to prevent oil, debris or other floating contaminants from exiting catchbasins through outlet pipes.
The skimmer baffles, cleanout pipe, and angles are primarily constructed of either galvanized steel, aluminum, polyvinyl chloride, polyethylene, fiberglass or acrylonitrile butadiene styrene. All steel components, other than stainless, shall be hot-dip galvanized. Mounting hardware, hinges, and latches are all stainless steel.
