Dandy Sack®

Most Reliable Drop Inlet Filter Available

The patented Dandy Sack® provides the best in storm grate filtration quality. The incredibly strong, open-top silt bag is specially designed to hang below the grate to expertly filter the thickest sediment-laden stormwater. The suspended solids are allowed to settle out of the slowed flow and are conveniently captured by the Dandy Sack prior to entering the inlet, making the reliable Dandy Sack a stormwater must.
