The bailey universal double worm screw is a drain clearing tool designed for removing stubborn blockages in drainage systems. This double worm screw attachment pierces obstructions such as paper or rags, allowing the blockage to be drawn back through the pipe to restore flow. With a 50mm 2 inch diameter, this universal drain rod accessory is ideal for tackling common drainage problems in domestic and light commercial applications. The double worm design provides enhanced gripping action compared to single screw variants, making it particularly effective when dealing with fabric based blockages that require a firm hold for extraction. The tool works by threading into the obstruction material as the drain rods are rotated, securing the blockage before it is carefully withdrawn. This method is suitable for clearing toilets, soil pipes and waste pipes where solid obstructions have become lodged.
