Cubis Systems manufacture and supply RAILduct™, a HDPE moulded cable trough system.

Weighing under 15kg and capable of meeting pedestrian loadings, RAILduct™ offers significant advantages in health and safety, speed of installation and flexibility.

Most importantly, laying RAILduct™ is typically 5 times faster than traditional concrete units, reducing the total cost of installation.

1 metre long sections are connected using the unique ‘Twist and Lock’ jointing mechanism which allows a small amount of movement to follow gentle curves in the track.

Cubis’ RAILduct™ has been installed in many rail applications throughout the world and in different extremes of temperatures. It also has the capability to be adapted for projects in power and highways applications.

RAILduct™ is type approved for use in TfNSW (Transport for NSW) networks.
