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

Description

The Storm Sentinel® Catch Basin Insert provides superior protection against harmful pollutants entering storm drains. This round, cone-style framed model includes an adjustable steel wire frame for a precise fit in drains measuring 25" to 28" in diameter, ensuring quick, one-person installation without special tools.

Designed with oil-absorbing packets for capturing oils and hydrocarbons in addition to sediment, this unit offers enhanced pollution control. Its geotextile fabric construction traps contaminated particles, while the low-profile placement beneath the grate makes it both efficient and discreet. The product is reusable until water flow capacity decreases and meets strict EPA, SPCC, and NPDES regulatory requirements.

Engineered for performance and compliance, this insert is ideal for use in Storm Water Pollution Prevention Plans (SWPPP) and carries U.S. Patent No. 10,384,155.
