Description
The Storm Sentinel® Catch Basin Insert is designed to effectively capture sediment, debris, and other pollutants before they enter storm drains, helping you stay compliant with EPA, SPCC, and NPDES regulations. This rectangular, cone-style model features an adjustable steel wire frame that accommodates drains from 16"x20" to 28"x36", allowing for quick and one-person installation without tools.
The geotextile fabric provides superior filtration, while overflow bypass ports manage high-flow events to prevent water backups. The cone design increases holding capacity without protruding above the grate. Units are reusable until water flow is significantly restricted, and an optional Spilltration® sorbent insert is available for capturing oils and hydrocarbons. Protected by U.S. Patent No. 10,384,155.
This SKU is sold as a box of 10 units, ideal for large-scale installations or multi-site maintenance programs.
