The Storm Sentinel® Catch Basin Insert is engineered to stop harmful pollutants and debris from entering storm drains. This frameless model offers a simple, cost-effective, and highly effective solution for stormwater protection in large drain openings. Designed for cut-to-size flexibility, it adapts easily to different dimensions while remaining low-profile beneath the grate for unobtrusive performance.
Constructed with durable geotextile fabric, the insert filters out contaminated sediment and can be used with an optional oil-absorbing Spilltration® sorbent insert for enhanced hydrocarbon capture. Featuring overflow bypass ports, it handles high-flow storm events without causing backups. The unit is reusable until it no longer maintains adequate water flow and installs without special tools.
