ENPAC Rectangular, Cone Style Storm Sentinel® Catch Basin Insert, Adjustable, Pallet of 300 (MPN: 4341-PT)

Description

The Storm Sentinel® Catch Basin Insert provides a reliable and efficient solution for preventing harmful pollutants, debris, and sediment from entering storm drains, ensuring compliance with EPA, SPCC, and NPDES regulations. This rectangular, cone-style model features an adjustable steel wire frame that fits drains from 16"x20" to 28"x36", allowing for fast, one-person, tool-free installation.

The geotextile fabric delivers superior filtration performance, while overflow bypass ports handle heavy stormwater flow to avoid water backups. The cone design offers increased debris capacity while maintaining a low-profile fit beneath the grate. Units are reusable until water flow becomes restricted. An optional Spilltration® sorbent insert is available for enhanced oil and hydrocarbon capture. Protected under U.S. Patent No. 10,384,155.

This bulk SKU contains a pallet of 300 units, making it ideal for municipalities, contractors, and large-scale stormwater management programs.
