The ENPAC Frameless, Cone Style Storm Sentinel® Catch Basin Insert, Box of 10 is designed to prevent harmful pollutants from entering storm drains. This frameless model is simple in design, powerful in protection, and one of the most affordable catch basin inserts available.
Its frameless design allows you to cut the fabric to size for a customizable fit. The inserts sit below the grate to maintain a low-profile and unobtrusive appearance.
Constructed from 8 oz. non-woven geotextile fabric, these inserts prevent contaminated sediment from washing into storm drains while maintaining adequate water flow. Standard versions include overflow bypass ports to handle high-flow storm events, preventing storm water backup around drains. The inserts are reusable until water flow is compromised and require no special tools for installation.
These inserts comply with regulations when used in Storm Water Pollution Prevention Plans and include an optional oil-absorbing Spilltration® sorbent insert to capture oils and hydrocarbons fully.
