‘J’ Junction Box
  The CBS Cable Overblowing Junction Box has been designed to install a new cable into an existing occupied sub-duct (subject to space being available). Or alternatively used for blowing micro tubes over previously installed cable.

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 can exit the Cable Overblowing Junction Box from either of the two branches to suit the best installation, the vacant branch is then connected to a CBS Cable Blowing Machine via a short slave length of sub-duct for the installation of the extra cable.

A range of customer selected cable seals, cable collets and sub-duct collets are available for cable or duct tube installation using the CBS Overblowing Junction Box.
