150/178mm Duct Coupler

This 178mm duct coupler is designed to connect 150/178mm twinwall ducting.

Ducting is designed to protect a service cable or pipe from damage and alert others to the presence of the duct in the ground. Marker tapes are commonly used as additional indications, alerting present service cables or pipes. Drawcord is commonly used to pull cables or pipes through ducting and duct access chambers are popular for allowing access to underground ducting systems. If you plan to run any type of service underground, it should be running inside a duct system.
