Description

The ENPAC Rectangular, Cone Style Storm Sentinel® Catch Basin Insert, Adjustable, With Oil-Absorbing Packet, Box of 10 (MPN: 4341-IB-BX) is designed to prevent harmful pollutants from entering storm drains. This framed model features an adjustable steel wire frame for simple installation and removal, allowing one-person setup without special tools.
