ENPAC Round, Cone Style Storm Sentinel® Catch Basin Insert, Adjustable, 25" to 28" (MPN: 4340-CONE)

Description

The Storm Sentinel® Catch Basin Insert is a dependable solution for preventing harmful pollutants from entering storm drains. This round, cone-style framed model features an adjustable steel wire frame for a secure fit in a variety of drain diameters, allowing for fast, one-person installation with no special tools required.

The overflow bypass ports are designed for high-flow storm events, helping to prevent stormwater backups around drains. Constructed from 8 oz. non-woven geotextile fabric, this unit effectively captures contaminated sediment while maintaining high water flow. The low-profile design allows it to sit discreetly beneath the grate, making it both effective and unobtrusive.

This product is reusable until water flow performance decreases and is fully compliant with Storm Water Pollution Prevention Plan (SWPPP) guidelines, meeting strict EPA, SPCC, and NPDES regulations.
