PIG® Stormwater Heavy Metal Filter Sock

Remove metals, oils and large amounts of sediment at any point along the stormwater runoff path with this economical sock designed for use on rough, uneven or exposed-soil surfaces.

• Filter substantial sediment from stormwater runoff to protect your stormwater drainage system; also catches oils and metals.
• Works great anywhere stormwater flows, whether at the source, the drain or in between.
• Metal filter sock captures copper, lead, zinc, chromium, cadmium and more.
• Filters 92.4% of total suspended solids (TSS).
• Strong outer skin is effective near light construction, in salvage yards and more.
• Sock stays firmly in place under its own weight, even on broken asphalt and dirt thanks to conforming internal material.
• For sloped areas, can be staked down.
• Easily bend the flexible 5-in. x 5-ft. sock around drains and conveniently move when needed.
• Recycled inner material (parboiled, oven-dried rice hull) never grows mold; won't release harmful compounds like rubber alternatives.
• Count on the 4.2 GPM/Linear Foot constant-flow filtration to resists water backup.
