Drain Seal for Spill Containment

The Enpac 4324-SP is a square urethane drain cover designed to create a positive seal over storm drains during spill response. It measures 24 inches by 24 inches with a quarter-inch thickness. The reusable design suits facilities managing hazardous liquid spills under EPA, SPCC, and NPDES standards. Fire-retardant properties are not included.

Limits of the Positive Seal Design

This cover fits drain openings up to 24 inches square and relies on material weight and flexibility to block flow. It does not use mechanical fasteners or adhesive, so sealing performance depends on surface condition and liquid head pressure. The urethane construction resists many chemicals but is not rated for fire exposure. Buyers needing larger coverage or bolt-down attachment cannot use this model.

Quarter-Inch Urethane Thickness

The 1/4-inch material thickness determines durability and conformability on uneven drain frames. Thinner seals may tear during deployment; thicker alternatives could reduce contact on irregular surfaces. This specific dimension balances reuse cycles with positive sealing capability for standard square drains. Specifiers should verify the thickness matches their spill-response protocol requirements.
