Abstract: A cable ladder formed by two side rails and crosspieces, all formed of extruded polymer material. The side rails have a channel receiving a corresponding end of the crosspieces. The channel has a lower rib and an upper rib. A projection of the lower rib or upper rib has openings along a longitudinal direction of the side rail. The ends of the crosspieces go through the opening of the projection and have a recess in which a corresponding portion of the channel is snap-fitted. The lower rib of the side rails is bent over itself along a bending line, such that a final section of the lower rib experiences downward expansion by elastic bending when the end of the crosspiece is introduced.

Abstract: A dowel inserted under pressure in a hole, including a head and a body which remain outside and inside the hole, respectively. The head is suitable for a clamp to pass through. The body includes a central core from which there emerge annular retention tabs having a slightly larger diameter than the hole, all provided with radial notches, and a centring annular projection. Each annular retention tab forms a pair with an annular abutment tab located, with respect to the former, in the position nearest the head. The annular abutment tab has a diameter that is smaller than that of annular retention tab and equal to that of the hole.

Abstract: Raceway for electrical cables having a channel-shaped base element made up of a flat bottom wall, and two side walls which form with the flat bottom wall respective blunt edges and which have a plurality of narrow cut-outs that are parallel and extend perpendicular to the flat bottom wall, and a series of slits arranged between the flat bottom wall and the narrow cut-outs. Each slit extends as far as the flat bottom wall, completely sectioning the blunt edge that the flat bottom wall forms with the side wall. The flat bottom wall is provided with a weakening line extending parallel to the blunt edge. The raceway allows a cable to be deviated through one of the side walls without having to deviate the cable vertically, by breaking away one of vertical flanges defined between the two narrow cut-outs.
