Description
The ENPAC Rectangular, Cone Style Storm Sentinel® Catch Basin Insert, Adjustable, 25"x25" to 42"x42" (MPN: 4343) is engineered to prevent harmful pollutants from entering storm drains. This framed model includes an adjustable steel wire frame for simple installation and removal, allowing one-person setup without the need for special tools.
Its low-profile design sits neatly below the grate, ensuring unobtrusive placement while effectively capturing sediment. The geotextile fabric prevents contaminated sediment from washing into the drain, and standard versions feature overflow bypass ports to handle high-flow storm events, preventing stormwater backup around drains. For enhanced protection, an optional oil-absorbing Spilltration® sorbent insert is available to capture oils and hydrocarbons.
Fully reusable until water flow performance declines, this insert complies with regulations when used in Storm Water Pollution Prevention Plans (SWPPP) and is covered under U.S. Patent No. 10,384,155.
