All-thread is threaded steel rod, usually 3/8 or 1/2 inch diameter in 10 or 12 foot lengths, hung from beam clamps, concrete inserts or anchors to carry trapezes, conduit hangers, boxes and fixtures. It is cut with a rod cutter that leaves clean threads, and nuts and washers can be set at any height along it. Some crews call it ready rod.
Drop two pieces of three-eighths all-thread from the beam clamps and we'll hang the rack at nine feet.
