ENPAC Frameless, Cone Style Storm Sentinel® Catch Basin Insert, Pallet of 300 (MPN: 4320-PT)

Description

The ENPAC Frameless, Cone Style Storm Sentinel® Catch Basin Insert, Pallet of 300 offers an efficient and affordable solution for preventing harmful pollutants from entering storm drains. This frameless model is simple in design, powerful in protection, and the most cost-effective catch basin insert on the market. The frameless design allows you to cut the fabric to size for a custom fit. These inserts sit below the grate, maintaining a low-profile and unobtrusive presence.

Made from 8 oz. non-woven geotextile fabric, the inserts effectively prevent contaminated sediment from washing into storm drains, while maintaining proper water flow. Standard versions come with overflow bypass ports to handle high-flow storm events and prevent storm water backup around drains. They are reusable until water flow becomes inadequate, requiring no special tools for installation.

These inserts comply with regulations when used in Storm Water Pollution Prevention Plans. There is an optional oil-absorbing Spilltration® sorbent insert available to fully capture oils and hydrocarbons.
