The Manthorpe SmartDrain Junction Unit is to be used when a 90º corner, T-junction or cross junction needs to be produced when laying the SmartDrain system. The Junction Unit has thinned out side walls which can be easily removed with a craft knife. Simply remove whichever and however many sides required and connect to the rest of the system with the easy to fix clips.

The junction unit is made up of the channel base and grate lid which falls into the channel, locating on its four location pins.
