The Storm Sentinel® Catch Basin Insert with oil-absorbing Spilltration® sorbent packet is engineered to protect storm drains from both sediment and hydrocarbons. This frameless model offers a cost-effective yet highly protective design, making it one of the most affordable and effective catch basin inserts available.
Its customizable, cut-to-fit fabric allows adaptation to different drain sizes, while low-profile, below-grate installation ensures it remains unobtrusive. The geotextile fabric filters contaminated sediment, and the integrated oil-absorbing insert captures oils and hydrocarbons for enhanced environmental protection. Overflow bypass ports help prevent water backup during high-flow storm events.
