ENPAC Rectangular, Cone Style Storm Sentinel® Catch Basin Insert, Adjustable, No Overflow, 25"x25" to 42"x42" (MPN: 4343-NO)

Description

The ENPAC Rectangular, Cone Style Storm Sentinel® Catch Basin Insert, Adjustable, No Overflow, 25"x25" to 42"x42" (MPN: 4343-NO) is engineered to prevent harmful pollutants from entering storm drains. This framed model includes an adjustable steel wire frame for simple installation and removal, enabling one-person setup without special tools.

Its low-profile design sits beneath the grate for unobtrusive placement while effectively capturing sediment. The geotextile fabric prevents contaminated sediment from washing into the drain. This version features no overflow bypass, making it ideal for applications where overflow ports are not desired. An optional oil-absorbing Spilltration® sorbent insert is available for enhanced oil and hydrocarbon capture.

Fully reusable until water flow performance declines, this insert complies with environmental regulations when used in Storm Water Pollution Prevention Plans (SWPPP) and is covered under U.S. Patent No. 10,384,155.
