PIG Drain Insert; 3 ft. L x 4 ft. W, Removes: Oil, Sediment

This PIG® Drain Insert Plus is an easy way to control oily runoff and sediment - and helps to avoid stormwater fines. Below-grate design stays intact in areas with high vehicle traffic. 18 in.-deep accumulation pocket collects oil, sediment, and other contaminants, but lets water flow through. Features 3 excess flow ports to prevent blockage during high water flow. Filter strips made from recycled fibers remove floating oil and other hydrocarbons. Trim excess fabric once grate is in place for neater appearance or leave untrimmed for easy maintenance. Ideal when you need to capture trash, sediment, silt, and hydrocarbons. Add strength and capacity by fitting heavy-duty retainer rods (sold separately) through attached loops.
