Unistrut is the brand that became the generic name for strut channel: a 1-5/8 inch square steel channel with inturned lips, cut to length and bolted into racks, trapezes and equipment frames. Spring nuts slide into the channel anywhere along its length to take bolts, and strut straps clamp conduit to it. Other makers include B-Line and Kindorf, and on some jobs Kindorf is the word everyone uses.
Build a trapeze off two pieces of all-thread and a four-foot length of Unistrut, then strap the three conduits to it.
