For Drain Connectors
GRAVEL-EXCLUDERS is used to stop dirt and various objects from entering the drain and obstructing the regular discharge of rainwater. We recommend cleaning the opening of the discharge from any dirt there may be.
It provides excellent resilience to deterioration caused by the sun, ozone and other weather agents or chemicals normally found in the atmosphere.
As well as keeping the drain clean, the gravel-excluder is used to contain the gravel used as ballast for waterproof felts. It just needs to be inserted into the drain connectors and with its small fastening bars it can be locked at the centre of the drain.
With its perforated grid, rainwater is drained quickly. The raw materials used guarantee a durable product, as the plastic materials are treated to ensure their mechanical properties remain unchanged.
