What are drain blockers used for?

Drain blockers are used to stop oil, fuel, chemicals and contaminated liquids from entering stormwater drains during leaks or spill emergencies.

What is the difference between drain blockers and drain plugs?

Drain blockers seal the surface of drain openings while drain plugs are inserted into pipes or drains internally to stop liquid flow.

Where are drain guards commonly used?

Drain guards are widely used in factories, warehouses, workshops, fuel stations, loading docks and chemical storage facilities for stormwater protection.
