A plurality of struts extend upwardly from a subfloor and a plurality of racks interconnect selected rows of struts for supporting transmission lines and/or conduits. Each strut is formed of four orthogonally oriented C-channels having the edge of each leg curled inwardly to define a lip extending toward the base and each rack includes a similar C-channel. Each end of each rack is detachably attached to a C-channel of a strut by a bolt penetrating a plate at the rack end and threadedly engaging a nut captured in the C-chanel of the strut. The transmission lines and conduits are secured to any of the C-channels of the struts and the racks by clamps having distal ends of two sections captured by the respective C-channel and an attachment mechanism securing the proximal ends of the sections to one another to retain the transmission lines and conduit clamped between the two sections. Disassembly of the transmission lines and conduits from the respective C-channels and disassembly of the racks from the struts involves unsecuring the proximal ends of each clamp from one another and withdrawing the distal ends of each clamp from the C-channel and disengaging the bolt from the captured nut.
