A 38mm wide UPVC channel is connected via downpipes at 200mm intervals to sockets in a 90mm drain below.

This allows the channel to be installed level while the drainpipe is given sufficient fall to be self-cleaning.

The Special Assembly is then completed with a grate from the AR, PH or PS series.

This system is unique in the world and was recognised for its innovation with a DesignMark at the 2004 Australian International Design Awards.
