These chambers fitted in national grid sites across the UK, have been specially fabricated to suit the customers requirements.

Constructed from twin wall pipe gives these chambers excellent crushing strength due to the nature of the corrugation on the pipe. A larger than necessary size has been used to allow the cover to be removed for the inspection of cables and connections, as well as any maintenance that may be required.

The main spigot allows cables to be fed to and from the chamber using conventional cable ducting.
