The Centaur PSB‑ADJ Series offers versatile, adjustable-depth switch boxes for new-work installations, featuring high-capacity cubic inches and robust steel bracket mounting. Available in 1‑gang (21 cu in), 2‑gang (34 cu in), and 3‑gang (49 cu in) options, each mold is constructed from flame-retardant PVC and paired with an adjustable steel stud bracket for precise alignment during framing work. All boxes come ETL-listed with a 2-hour fire rating and are cULus compliant. Pre-punched ½″ knockouts and integrated cable clamps ensure easy entry and secure routing of conductors, while gray PVC provides durability and electrical insulation. Manufactured in China, these boxes offer professional-grade performance for residential and light commercial wiring projects.
