ENPAC Frameless, Cone Style Storm Sentinel® Catch Basin Insert, No Overflow, 60" X 60" (MPN: 4326-NO)

Description

The Storm Sentinel® Catch Basin Insert is engineered to stop harmful pollutants, sediment, and debris from entering storm drains. This frameless model offers a simple yet highly effective design, making it one of the most affordable catch basin inserts available.

Built with cut-to-size geotextile fabric, it allows quick customization to fit various drain openings. The low-profile installation beneath the grate keeps it discreet while ensuring maximum performance. The no overflow bypass version provides continuous filtration without bypass ports, making it ideal for areas where strict sediment control is required.

Designed for easy, one-person installation with no special tools, this insert is reusable until its water flow performance can no longer be maintained. Optional oil-absorbing Spilltration® sorbent inserts are available to capture oils and hydrocarbons, enhancing environmental protection.
