It installs under the grate using a high-flow woven filter fabric to retain sediment, silt, and debris while allowing runoff to pass through to the drain. Once installed, accumulated material can be removed from street level with basic tools, reducing the need to lift or remove the grate during routine maintenance.\u003c\/p\u003e\n\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e28\" x 42\" Inlet Coverage\u003c\/strong\u003e – Sized to fit 28\" x 42\" (711 x 1,068 mm) storm drain grates, providing full under-grate coverage for sediment and debris control in flat grate catch basins.\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eSediment-Only High-Flow Filtration\u003c\/strong\u003e – High-flow woven filter media captures debris, sediment, and silt while maintaining flow through the drain in a sediment-only, no-overflow configuration.\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eUnder-Grate Installation\u003c\/strong\u003e – Installs beneath the storm drain grate as an insert, allowing the grate to remain in place while the filter collects material from incoming runoff.\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eStreet-Level Maintenance\u003c\/strong\u003e – Sediment and debris can be removed with a broom, flat shovel, or similar tool from street level, minimizing grate handling and simplifying maintenance.\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eDurable Woven Construction\u003c\/strong\u003e – Manufactured with high-flow woven fabric and hi-vis polypropylene construction, with a 2 lb (0.9 kg) unit weight suitable for repeated use in stormwater programs.\u003c\/li\u003e\n\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eProduct Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ctable border=\"1\" cellpadding=\"8\" cellspacing=\"0\" style=\"border-collapse: collapse;
