ENPAC Round, Bag Style Storm Sentinel® Catch Basin Insert, Adjustable, 22" to 24"(MPN: 4340-22)

Description

he Storm Sentinel® Catch Basin Insert is engineered to help prevent harmful pollutants from entering storm drains. This round, bag-style framed model includes an adjustable steel wire frame that fits drain openings from 22" to 24", ensuring quick, one-person installation with no special tools required.

Its low-profile design sits neatly beneath the grate, allowing effective sediment and debris filtration without obstructing foot or vehicle traffic. The geotextile fabric captures contaminated sediment while the overflow bypass ports handle high-flow storm events, reducing the risk of stormwater backup. Fully reusable until its water flow performance decreases, it complies with EPA, SPCC, and NPDES regulations.

Multiple sizes and custom configurations are available to suit different site requirements, making this an excellent choice for Storm Water Pollution Prevention Plans (SWPPP). Covered under U.S. Patent No. 10,384,155.
