The Y-Connector is used to optimize available space in an existing occupied duct and allow for installation of a second cable, or multiple microducts when "jetting, blowing or floating" cables. For cables Ø 9 to 36 mm and ducts OD 20 to 63 mm. Performance obtained corresponds to at least 50% of the one achieved with the first cable. One branch of the Y-connector, connected to the machine is used for feeding the second cable in the duct. Installation distance achieved with two additional cables is nearly the same as the one obtained with one cable.
