Description
The ENPAC Rectangular, Cone Style Storm Sentinel® Catch Basin Insert, Adjustable, With Oil-Absorbing Packet, 16"x20" to 28"x36" (MPN: 4341-IB) is designed 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 special tools.
Its low-profile design sits neatly below the grate, preventing obstruction to foot or vehicle traffic. The geotextile fabric captures contaminated sediment, while standard versions include oil-absorbing packets for enhanced pollutant control. Fully reusable until it no longer maintains adequate water flow, this insert complies with environmental regulations when used in Storm Water Pollution Prevention Plans (SWPPP).
Covered under U.S. Patent No. 10,384,155, it offers a versatile solution for rectangular drains of varying sizes.
