Abstract: A support clamp for releasably mounting items on a support bar (19), comprising a locking body (1) and a support body (2) which under a mutual locking engagement are movable vertically in relation to each other and between which there is a locking means comprising a locking ball (13) which is vertically displacable in a guide bore (15) and an actuation ball (14) which co-operates with the locking ball (4) and which is horizontally movable in a guide bore (16) communicating with the guide bore (15) of the locking ball (13), and in which the actuation ball (14) is arranged to be actuated to a displacement in the guide bore (16) by an actuation groove (17, 18) in the support body (2), whereby the locking ball (13) when moving the support body (2) upwards in relation to the locking body (1) slides down in its guide bore (15) thereby releasing the support clamp, whereas the locking ball (13) when moving the support body (2) down in relation to the locking body (1) is forced upwards and partly out of the guide bore

Abstract: 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.
