Abstract: A duct (10) is made up of a plurality of layers (11, 12, 13) of pliant material. The layers (11, 12, 13) are attached by stitching (20, 22) to form pockets (23, 24) between adjacent layers. One of the layers (11) is wider than the others and extends over the lateral edges (17, 19) of those layers (12, 13), and when the stitching (22) is applied, a loop (21) is formed. The loop (21) receives a strength member (26) which may be engaged by a clamp (31) carried by a bracket (34) which may be attached to a utility pole (30) to carry the duct (10) overhead. In another embodiment, a duct (40) includes enclosed loops (41, 42, 43) forming pockets (50, 51, 52). Stitching (54) connects the loops (41, 42, 43) and forms another loop (55) to receive a strength member (56). In yet another embodiment, the layers (61, 62, 63 and 64) are of different lateral widths, and the longest layer (64) extends around one of the edges of the other layers (61, 62, 63) to form a loop (71) when stitching (65) is applied.

Abstract: A system for dividing a conduit (12) into a plurality of compartments (20-24) includes an insert (10) which is formed by attaching a plurality of layers of a pliant material (14-17) near their lateral edges (18). The insert can be formed with a cable (25), a rope (26) or a tape (27) pre-positioned between the layers (14-17) or the cable (25), rope (26) or tape (27) can be positioned in the respective compartments (20-22) after the insert (10) is installed in the conduit (12).
