Abstract: A conduit support assembly comprising the combination of a base member and a bridge member for positioning and securing a plurality of conduits upon a rooftop surface. The support assembly base member is configured to be fixedly attached to a substantially flat rooftop surface. The bridge member is longitudinally disposed above this base member and has a pair of vertical brace members—one at each end of the bridge member. Each of the pair of brace members is affixed to the base member with a pair of legs. Disposed between the pair of brace members is a transversal member disposed parallel to and above the base member. The bridge member is configured to receive conduits disposed longitudinally atop the transversal member and also a plurality of conduits disposed in a space medial of the base member and the transversal member. Each of these various conduits is secured to the conduit support assembly with a suitable damp.
