A module for conducting each of a plurality of fluids from a source thereof to a desired delivery location along a wall comprises a horizontally elongated body having therein a plurality of lengthwise extending bores, one for each fluid, that are spaced apart vertically. On an upright front surface of the body there are a plurality of linear indicia, preferably V-grooves, one for each bore. Each indicium is contained in a horizontal plane that also contains the axis of its bore, so that an outlet from each bore can be formed anywhere along its length by drilling rearwardly into the bore from its indicium. The body has a uniform cross-section along its length to be suitable for extrusion, and it includes an attachment portion and portions that provide a dust seal between it and a wall to which it is attached.
