Overview

The ABB 72171 1 1/4 Square Box is a pre-galvanized steel electrical enclosure designed for industrial and commercial conduit installations. This welded-steel box measures 4-11/16 inches square by 2-1/8 inches deep, providing 42 cubic inches of internal volume for routing and terminating electrical wiring. The box features 3/4-inch and 1-1/4-inch eccentric knockouts on all sides, allowing flexible conduit entry from multiple angles without the need for additional drilling or modification. Constructed from corrosion-resistant pre-galvanized steel, the enclosure resists rust and degradation in harsh environments, extending service life in wet, outdoor, or chemically aggressive locations. The welded construction ensures structural integrity under mechanical stress and vibration, making it suitable for heavy-duty applications such as machine control panels, distribution boards, and junction pull boxes. With a UNSPSC code of 39121308 and manufactured in the USA, the 72171 meets rigorous electrical installation standards for reliability and safety. Its compact footprint and high cubic capacity make it ideal for space-constrained installations where conduit routing flexibility is critical. The box is compatible with standard 3/4-inch and 1-1/4-inch rigid or EMT conduit systems, supporting both threaded and non-threaded connections. Suitable for use in NEC-compliant electrical systems, this box supports branch circuits, feeders, and control wiring in commercial buildings, industrial facilities, and utility installations.
