For the best results in curb inlet filtration, the rugged patented Dandy Curb Sack is extremely popular because it can handle jobs big and small and can be reused again and again. With an open-top design it fits to any size curb inlet and gutter inlet. Its unique design allows it to filter sediment-laden water with ease. The suspended solids are allowed to settle out of the slowed flow and are captured quickly by the Dandy Curb Sack before entering the inlet. Once you?ve tried the durable Dandy Curb Sacks you?ll want to use them on every job.
