Industrial 72C1 Electrical Box

Steel City 72C1 is a pre‑galvanized steel square electrical box cover, 4-11/16 in. square, intended for flush mounting over a matching 4-11/16 in. square box in industrial or commercial installations. This flat, blank cover has no knockouts, providing a clean exterior face while allowing access for future wiring work. It carries UL E2969 listing and CSA recognition, reflecting Steel City’s compliance standard for metallic boxes and covers. The 72C1 label identifies a square cover designed to fit standard 4-11/16 in. square boxes within Steel City’s family of covers and accessories, making it a common choice for utility rooms, corridors, and commercial spaces where a durable, unobtrusive finish is required. Constructed for durability in damp or humid environments typical of many industrial settings, the cover’s steel construction and pre‑galvanized finish help resist corrosion over time, while preserving a simple install or swap‑out should future configurations be needed.
