An adapter chamber 100 is configured to be connected to a blowing machine via air entry point 23 and used for introducing a second cable SC and optionally, a third cable TC, into a conduit in which a first cable FC is already provided, the adapter chamber comprises a first slot 15 for receiving the first cable and a second slot 16 for receiving the second cable; and optionally a third slot 17 for receiving the third cable. The method of installing a second, third or subsequent cable into a conduit in which a first cable is already provided, comprises; cutting a sub duct at a start point of the proposed new ducting route for the additional cable so as to allow the insertion of the second cable and optionally, third cable, through the sub duct; positioning an adapter chamber 100 at or on the blowing machine; and introducing air under pressure directly into the sub duct using the adapter, for delivery of the additional cable(s) into the sub duct. |
