<p>PURPOSE:To lay a cable duct easily in a sewerage and drain conduit by bending inward one side of the opening of a telecommunication cable duct C-shaped in cross section and by providing a hole corresponding to an upper bolt-fitting hole. CONSTITUTION:One side of the opening of a cable duct 7 C-shaped in cross section and opened in the axial direction is bent to form a bending part 9. Holes 10 for passing an anchor bolt 4 are provided at both ends of said duct 7 to engage said anchor bolt 4 driven in the ceiling or upper part of a sewerage and drain conduit. In the position corresponding to said holes 10, holes 11 are provided to facilitate the insertion of a nut and nut-driver 8. In this manner, the laying work of a cable 2 in the sewage and drain conduit 1, where sewage water 6 flows, can be performed easily.</p> |
