4‑Inch Square Device Box – Galvanized Steel, 1.1 mm, ETL Listed

This 4‑inch square junction box offers ample space for splicing multiple conductors or mounting receptacles and switches. Made from heavy‑gauge 1.1 mm galvanized steel, it resists corrosion and stands up to job‑site abuse. The drawn design provides a spacious interior for wire connections, while concentric ½‑ and ¾‑inch knockouts on all sides and the bottom simplify conduit runs and cable entry. An integral grounding screw ensures safe device grounding. Four‑inch metal boxes like this are the standard junction box for wiring splices because they provide sufficient volume for multiple wires. ETL‑listed (4009580) and available individually or in convenient 40‑pack cartons, it’s ideal for new construction or renovations.
