The CBS Cable Overblowing Junction Box has been designed to install a new cable into an existing occupied sub-duct. The Cable Overblowing Junction Box comprises a robust aluminium base and lid that form a pressurised air chamber into which one end of an existing occupied sub-duct can be attached.
The existing cable exits the Cable Overblowing Junction Box through an opening that has 3 cable seal slots, one of which will house the seal to suit the size of the existing cable. The third branch is then connected to a CBS Cable Blowing Machine via a short slave length of tube for the installation of the extra cable.
