A flexible partitioning device (10) for a tubular conduit (11) includes an elongate web member (22) which can be provided with a plurality of notches (32) spaced substantially regularly along its length to permit multiplanar articulation thereof. The web member (22) may also be provided with a longitudinally extending strength member (20) and may also include at least one bore (50) in which may be positioned a transmissive element (51). The partitioning device (10) may be connected to a duct rodder (61) and pushed through the conduit (11) or alternatively, the duct rodder (61) can be attached to a paddle (64) which is pushed through the conduit (11). Then, the partitioning device (10) is attached to the duct rodder (61) and pulled back through the conduit (11). To assist in pushing the rodder (61) through the conduit (11), an air moving device (73, 76) may be attached to one of the ends of the conduit to move air in the same direction of travel as the rodder (61). The partitioning device (10) may also be pulled through conduit (11) by a rope (42) wherein device (10) has apertures (81) for receiving ropes (82) or cables (86). As the partitioning device (10) is pulled, ropes (82) and/or cables (86) are also pulled through conduit (11). Then, a cable can be attached to rope (82) and pulled back through an appropriate chamber of conduit (11).
