ENPAC Frameless, Cone Style Storm Sentinel® Catch Basin Insert, Box of 10 (MPN: 4326-BX)

Description

The Storm Sentinel® Catch Basin Insert is designed to block harmful pollutants, sediment, and debris from entering storm drains. This frameless model combines simplicity, durability, and cost-effectiveness, making it one of the most affordable catch basin inserts available.

Its cut-to-size geotextile fabric allows for easy customization to fit various drain openings, while the low-profile design keeps it unobtrusive beneath the grate. The unit includes overflow bypass ports to handle high-flow storm events without flooding and can be enhanced with an optional oil-absorbing Spilltration® sorbent insert to capture hydrocarbons.

Installation is quick, requires no special tools, and can be done by one person. The insert is reusable until water flow performance is no longer adequate, making it a long-lasting stormwater management solution.
