ABSTRACT:
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).
