100mm Drainpipe with 65G UPVC Channel

The Special Assembly is a narrow profile, high capacity drainage system that allows flexibility in outdoor design and construction, including wet-edge or infinity pool situations, patios, driveways etc.

This patented manifold drainage system reduces the need for traditional wider grating.

The 65G100 is a 65mm wide UPVC channel that is connected via downpipes at 200mm intervals to sockets in a 100mm 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 65mm wide stainless steel grate from the AR (wedgewire), PH (punched hole) or PS (slot punched) series.

This unique drainage system was recognised for its innovation by a DesignMark at the Australian International Design Awards.
