ABSTRACT:
Modular support systems constructed from a plurality of transportable modular components which are capable of being rapidly assembled and disassembled at an on-site location. The support systems are capable of being assembled into shelves, platforms, ladders, walkways, and like structures, and may be attached to existing structural members. The support systems are comprised of a plurality of rails and metal rungs for extension between and attachment to the rails in a variety of positions to form various structures. The rungs are provided on each of their opposite transverse ends with tabs capable of fitting through complementary slots in the rails. The tabs may be displaced so as to make the ends of the rungs captive in the rails. The modular support systems also include various other components such as vertical risers, 90.degree. bends, tees, reducers, and the like. These various components may also be provided with the tabs and corresponding complementary slots for assembly and disassembly to form the various structural members. In addition, suspension rods are also provided for use with the various components to supportively suspend its various structural members. In the preferred aspect these support systems are used for holding and retaining electrical cables, conduit, and the like.
