24-inch Catch Basin Insert

The Enpac 4341-IB catch basin insert measures 24 inches long, 36 inches wide and 21 inches high. It is built from black non-woven geotextile fabric designed to remove debris, hydrocarbons, oils, sediment and trash from stormwater runoff. The unit fits drains ranging from 16 by 20 inches up to 28 by 36 inches. It suits facilities managing stormwater compliance.

Flow capacity and oil retention

The insert handles a flow capacity of 500 gpm while capturing contaminants. Its oil capacity is 0.23 gallons, limiting the volume of hydrocarbons it can hold before replacement. Sediment and trash accumulation will also reduce effectiveness over time. Regular inspection is required to maintain performance.

Drain dimensions and maintenance access

Verify that the existing drain opening falls within the 16 by 20 inch to 28 by 36 inch range before ordering. Confirm there is enough clearance to insert and remove the 21-inch-high unit for cleaning. The fabric construction requires periodic replacement once saturated with oil or clogged with sediment. Plan for disposal of spent inserts.
