Commercial electrical raceways — RACO short elbows (e.g., 1/2 in and 3/4 in iron elbows) change direction in IMC and RMC runs per UL 514B.
Panel and equipment wiring — RACO flex screw-in couplings (e.g., 2272) join sections of 1/2 in flexible conduit between machines and junction points.
Raceway transitions — RACO flex-to-EMT couplings (e.g., 1482, 1483) connect flexible conduit to EMT in mixed raceway installations.
